1981 Porsche 911SC Coupe “RS” Backdate

We come across a lot of backdated 911s in a wide variety of builds though nearly all based on a similar premise: the underpinnings of the 911SC or 3.2 Carrera mated to vintage long-hood 911 Carrera RS styling. A common version I’ve seen is kind of a Frankenstein: a 911SC chassis with a 3.2 Carrera engine and that RS styling. As with any build, quality can be almost as variegated as the color palettes. I like the idea and many of them look great and provide something that many 911 fans find quite desirable. Not for all, since purists will always cherish originality, but the variety makes the market more intriguing and might even give buyers some ideas of their own.

This one, at least on appearance, is a pretty interesting one. It is photographed well and that always helps these cars stand out because their colors tend to play up contrasts more so than a standard 911. It also comes across as a fuller package though not necessarily pushed to the limits. They’ve done not only exterior and interior treatments, but they’ve also put in some effort to bring a vintage quality to the engine by fitting Weber carburetors and generally restoring it to pristine shape. The details certainly won’t excite you like something from Singer – I don’t think there’s anything here that we’d call bespoke – but the overall execution looks solid and the selling price should be significantly below that of a Singer. As an alternative to a standard 911SC or 3.2 Carrera this might make for an interesting option.

I always struggle to come to terms with pricing of these builds. In part, that’s because there’s so much subjectivity to the pricing. And in part, it’s because I know there is typically a lot of work been put into these builds and that can be difficult to properly value. If the right buyer comes along a seller could likely extract quite a premium. But waiting for that buyer might require more patience than some sellers are willing to tolerate. Bidding here sits at $46,300 and the reserve is unmet. How high will it go? I have no idea! $60K? Perhaps higher for that perfect buyer. Given how often I’ve seen builds optimistically priced above $100K I never quite know what to expect. In many ways the donor car and engine will tell us a lot. The SC and 3.2 Carrera builds, when more or less maintaining their original power levels, shouldn’t see too high of a price. One based on the 964, or even more rare showcasing a 993 engine, fall into an entirely different tier and with those we can really have something special with a price to match.

For a 911 like this I tend to think of it as being a really nice 911SC that’s had a good bit of work to return it to spirited and pristine form. There is value to be had there, though not necessarily as much as an original SC in comparable condition. And that’s where the pricing becomes difficult. I suspect many buyers will lose interest once the price drifts too far above $50K, but if the drive is as delightful as the appearance then I’m sure some can be persuaded to pay more.

  1. If somebody wants to indulge their fantasies by building one of these clones/tributes/recreations/replicas/whatever, fine, it’s their car and their money, but unless you’re building a true tool-room copy, at least leave off the Carrera and RS decals so it isn’t a total fake.

  2. This car is a really nice build for what it is. There is a lengthy thread documenting the build over on Pelican. This the builder sold it on Pelican its changed hands several times from dealer to dealer getting more expensive each time. This car was also recently run on BaT and the auction ended with a high bid of $69,500 and a no sale.

    This happens to be a very nice car, but with fiberglass fenders, bumpers and hood $69,500 is really all the money. The air cooled hot rod market is still hot. We have seen some really well done ones with steel fenders go for big bucks. As nice as this car is, its not in that league. My 2 cents is that the seller would have done well to hit the $69,500 bid. I would also lose the duck and the graphics and make it more sublime.
