1983 Porsche 911SC Coupe 5-Speed

Up for auction is this 1983 Porsche 911SC Coupe finished in Quartz Grey Metallic over a brown interior.  Shown to have been under the care of its original owner in Connecticut up until 2006, this 911SC eventually made its way to the seller in Florida who had recently carried out extensive maintenance in preparation for sale including valve adjustments, new brakes, fuel system and ignition system, belts, filters, gaskets, and more.  Representing the final model year of the 911SC, this 1983 example is now being offered for auction by its seller out of Florida with approximately 57k miles showing on the odometer.

The Quartz Grey Metallic (662) finish is described by the seller as being mostly original and beautifully presented while free of any major flaws.  The hood and rear decklid are said to have been previously refinished to correct some cosmetic imperfections.  Detailed images are provided in the photo gallery.  Exterior features include a front spoiler, fog lights, impact bumpers, black stone guards, and classic 16” Fuchs allow wheels that are currently dressed in Michelin Pilot tires from 2019.  The car has also been lowered to European ride height for a more aggressive stance.

Inside, you will find a brown interior with contrasting black accents on the lower dashboard and door handles, and side pockets.  Amenities include an upgraded Polk Audio stereo and speakers as well as factory power windows, sunroof, power mirrors, and Porsche-logo floor mats. The factory air conditioning system was recently serviced and is said to be working properly along with all other gauges and accessories.

This 911SC derives as much as 180 HP from its air-cooled 3.0 L flat-six engine.  The rear wheels are driven through a 5-speed 915 manual transmission.  This 1983 example is especially desirable for its Carrera engine case which was carried over to its successor the following model year.  In preparation for the sale, the seller commissioned a recent full service that included valve adjustments, new brake pads and rotors, a new fuel accumulator and filter, an oil change, new hood and deck struts, belts, a new air filter, and timing chain gaskets, as well as a new ignition cap, rotor, wires, and spark plugs.

This sale will include a set of two keys, owner’s manuals, a toolkit, air pump, some service records, and a clean title.  A beautiful air-cooled Coupe with a long list of recent maintenance items, this 911SC is just waiting to be driven and enjoyed by its next owner.

    @VertexAuto I fell in love with this car the first time I saw it. Unfortunately when you live across country and can’t see the car in person, you have to rely on the sellers description, past records, and questions asked during the auction. When obvious things are missed it throws up red flags. Miscommunication, the previous auction, and not answering certain questions doesn’t help. I’m keeping a close eye on this. Once again, Good luck.

  • VertexAuto (seller) 3 weeks, 3 daysago

    @RAL Now you are just hurting my feelings. I try to do the best I can describing the cars we sell. I do make mistakes, but I always try to correct my mistakes as best as possible. I believe that is "integrity". We have sold quite a bit of cars here on Pcar and hundreds throughout the years. I believe that we have done right by our buyers. Most of the time going above and beyond to make sure that they were pleased with the decision to trust us with the purchase of their Porsche. I do apologize for falling short on this on for you. I hope there is a next time.

  • RAL (registered bidder) 3 weeks, 3 daysago

    @VertexAuto @Vertex auto

    Wow! So much missed. You missed running the VIN when you bought the car, then you missed something as important as a valve adjustment, when you clearly stated work had been commissioned, but then could not produce proof of any of that work. I think what was missed mostly was the integrity of of this auction. Good luck.

  • VertexAuto (seller) 3 weeks, 4 daysago

    We are down to the last few hours of this auction. Thanks to all the commented, bid, called, and came to see the car. We'll make ourselves available until the end of the auction for any questions or requests.

    We submitted 4 pics of each of the bare metal floors under the factory floor mats. They look to be in very good condition with no signs of rust, mold, or water damage.

  • VertexAuto (seller) 3 weeks, 4 daysago

    @RAL Maintenance on these cars should be performed based on time and not mileage, since they are rarely driven. It's not uncommon to perform routine maintenance 12-18 months later regardless of how much it was driven.

  • VertexAuto (seller) 3 weeks, 4 daysago

    @bannedfromESR I agree on the valve covers. That was my mistake. A miscommunication between the shop and I. I'll honor the listing and perform a valve adjustment prior to delivery of the vehicle if the winning bidder requests. Not my intention to falsely claim anything that was done to the car or the condition of the car. Thank you!

  • VertexAuto (seller) 3 weeks, 4 daysago

    @teescott We won't have enough time to do a leak down and compression test prior to the auction ending. However, we always allow the winning bidder a PPI prior to purchase payment.

  • trailhalsy 3 weeks, 4 daysago

    Bid in the amount of $40,005

  • teescott 3 weeks, 4 daysago

    It would give a lot of confidence for this car's engine condition if the seller would post current compression and leakdown results for the engine. Is that possible?

  • RAL (registered bidder) 3 weeks, 5 daysago


    I feel the same. In an earlier comment seller says “ looks like engine was rebuilt or resealed, replaced chain tensioner, alt fan, ign wires - Appears a lot of money was spent between BaT auction and now “. In Pcar description seller claims to have commissioned a full service , to include valve adjustment, belts, fuel filter, ( which is subjective ) air filter, oil change, and front rotors and pads. With very few miles driven ( 57K ? ) why would a full service be needed? Wouldn’t most of those items have been done during the rebuild? Also during BaT auction that seller claimed new front rotors and brake pads installed. Again, why would it need to be done again with little to no miles driven? Strange at least...

  • bannedfromESR 3 weeks, 5 daysago

    @VertexAuto "we don't have service records but the car speaks for itself."
    Yes, it certainly does.
    Looking at the barnacles and corroded nuts I'm guessing those valve covers haven't been off since the Clinton Administration.

    In the first paragraph of the auction description it states "recently carried out extensive maintenance in preparation for sale INCLUDING valve adjustments". Honest question: If you don't have records how can you say that?

    This looks like a fantastic car but those of us who actually make our living servicing these cars every day get weary of descriptions that are not forthright. Just be honest or do the hard work of prep begore bringing to market. Thanks.

  • VertexAuto (seller) 3 weeks, 5 daysago

    @RAL No, we did not buy it from the BaT listing seller. The only respray I can see/know of is the Hood (to address the scratches you mentioned) , Rear Deck (after the spoiler was removed), and the Sunroof. I'll double check that right rear fender area you mentioned and let you know what I see.

  • RAL (registered bidder) 3 weeks, 5 daysago


    A couple more questions. Did you purchase the car from the BaT listing seller? How much respray does the car have? I see where there was slight fender damage behind right rear tire, also there were three marks on the front trunk near the P badge that are now gone.

  • VertexAuto (seller) 3 weeks, 5 daysago

    @Skibum I apologize for the delay in response. I had to do some unexpected traveling.
    Great find! I normally search vin numbers before I purchase a car, I guess this one slipped by me. I did see the comment that someone made stating that the car was previously for sale in Rutland Ma and that the interior "was a moldy mess". I have no idea if that is true but what I can tell you is that this is one of the cleanest SC interiors I've seen, and it still has the distinct "Porsche Smell". The steering wheel has been reupholstered and it has an aftermarket MOMO shift knob. Other than that, the interior looks to be 100% original including all the carpets and mats. In the video I posted I show the condition of the original mats and the bare metal floor board. Everything looks great! I'll take some close up pics and post by tomorrow.

    Comparing the pics from the BAT listing, it looks like the engine was taken down and either rebuilt or resealed. I assume that at that time some upgrades were made and parts were replaced, like the the Carrera chain tensioners, alternator fan, ignition wires, engine sound pad, exhaust etc. It appears like a lot of money was put into the car between the time it was on BAT and now. Unfortunately, we don't have the service records but the car speaks for itself. Thanks again and let me know what other questions you may have.

  • VertexAuto (seller) 3 weeks, 5 daysago

    @Jackallensmith I know that the car does have updated Carrera chain tensioners, as seen in pictures 61 & 97. The '83 SC always came with spring centered clutch discs so no update is needed on this model. I checked for a pop-off value on the air box and this update has not been performed yet.

  • RAL (registered bidder) 3 weeks, 5 daysago


    Will you reply to the late questions about interior smell and floor pan condition? Also, the Puralator fuel filter? Thx.

  • Jackallensmith (registered bidder) 3 weeks, 6 daysago

    @Skibum great detective work! I tried to like it but I think my fat thumb hit the inappropriate button - not my intention. Sorry.

  • bannedfromESR 3 weeks, 6 daysago

    @VertexAuto BTW: Was the fuel filter changed when the tune up was done? That's a Purolator which means it's most likely been on there a very, very long time. Those haven't been available for 10-15 years.

  • bannedfromESR 3 weeks, 6 daysago

    Looks like a very honest car; trunk is super original which is always a good sign. Not crazy about the used car treatment in the engine bay... aftermarket coil and rattle-canned alternator fan are tacky. Also, cryo blasting the bottom of the motor would have paid off in spades and whoever installed the tensioner kit was a slob.

    "1983 was especially desirable for its Carrera engine case" Huh? Alu cases with the strainer plate actually have an advantage because one can "see" what's happening inside when inspecting the strainer.

    Best of luck. Looks like a great car.

  • Skibum (registered bidder) 3 weeks, 6 daysago

    This car was on BAT back in July 2019. Buyer backed out and the seller disappeared based on the comments - found it by the VIN. There was talk that it had sat out in a field for awhile and the inside seemed moldy. Based on the pics today one can see that the engine bay was cleaned up and decals removed/replaced, a turbo was wing was removed and the old aftermarket exhaust was replaced with what appears to be a stock system. Anything else done since 2019? Any comments in the interior and how the metal is below the carpet? Thanks!

  • Jackallensmith (registered bidder) 3 weeks, 6 daysago

    Beautiful car. Has any of the potential SC issues been addressed: rubber centered clutch replacement with spring centered unit; installation of pressure fed tensioners; installation of spring loaded pop-off value on the air box?

  • VertexAuto (seller) 4 weeksago

    @Steviebatz @Clint930 I just summited some pictures of the undercarriage. I also removed the wheels and photographed the brakes and wheel wells. The pictures show some of the work that was recently performed including new brake calipers, slotted rotors, pads, stainless-steel brake lines, etc. A new factory original oil cooler was also recently installed.

  • VertexAuto (seller) 4 weeksago

    @Midmich60 Thank you! Yes, it looks like 200 miles or so in that time. Unfortunately, we really don't have a lot of info about the previous ownership or how the car was stored.

    I will say that the weather-strappings around the car are not dry at all and look very healthy. As for the engine, we inspected it for leaks and did not find any. From what we can tell, the engine was recently rebuilt.

    I personally drove the car several times and it really needs nothing. Well, I would upgrade the tie rods to the turbo style but that's optional. Suspension feels good, transmission shifts flawlessly, and the engine is very strong. The car drives great! One of the smoothest 915s I've ever driven, hands down.

  • VertexAuto (seller) 4 weeksago

    @Clint930 Thank you! By far my favorite SC of all the ones we have ever sold. The color is even more fantastic in person, and the interior is super clean and very original. I just summited pics of all the seats, front trunk, under side of the engine, and paint meter readings around the car. I also submitted a cold start and walk around video. I'm sure @Pcar will post those shortly.

    I hope to get the car up on the lift later today so I can get better pics of the underside.
