Modified cars are an acquired taste, but one thing is for sure: it’s hard to get the same money for a car that’s been tinkered with versus one that’s bone stock. The Porsche 911 is a car that usually fares much better when found in stock condition, but before the air-cooled market blew up, plenty of these used sports cars were considered ripe for tuning up. This 1980 Porsche 911 Cabriolet listed here on Facebook Marketplace has been heavily modified with a slant nose and wide body conversion, an engine swap from a 1980s-era Turbo, and a host of other upgrades. The asking price is $105,000.

There was a time when the Porsche 911 was not the sacred cow it now is. The aftermarket loved the 911, and often followed what the factory offered as upgrades to well-heeled customers with a more affordable copy or clone of the OEM offering. One of the best examples of this is the wider arches of the factory Turbo model since everyone loves a widebody. While plenty of fiberglass kits were available, the best clones of Porsche’s highest performance model used all-metal components. In addition, when Porsche began offering a slant nose conversion – featuring pop-up headlights – this, too, became a wildly popular aftermarket offering. The question is, what is the value of upgrades like these, especially compared to a bone-stock car?

The truth is, it all comes down to the quality of the execution. The seller reports that the slant nose conversion is all metal, but doesn’t say boo about the wider rear arches. The interior is in fair shape overall, but it clearly hasn’t been restored. It shows “comfort”-grade seats, which aren’t nearly as desirable as sport buckets. The aftermarket steering wheel was a fairly popular option in the 80s, and in this instance, I’ll argue that it’s a better look than the stock wheel. The seller notes a variety of recent maintenance, including fresh steering and shifter bushings, new soft brake lines, clutch master and clutch slave replaced, and new Pirelli tires all around.

The engine is a rebuilt 3.3L turbocharged flat-six with an aftermarket turbo and dual port wastegate. The seller lists off a few other upgrades and repairs, and also notes it has the desirable G50 manual transmission. However, some of the details let this car down, like the fact that the respray extended to the top of the tail light housing, which should simply be exposed black plastic. The factory stickers are also missing off of the engine bay, and may have been painted over as well. As modified cars, you simply don’t know to what quality level the work was done, which makes the asking price slightly ambitious in a segment that strongly favors bone stock cars.
