While aftermarket convertible conversions can be a take-it-or-leave-it affair, some of them really do turn out quite well. This 1984 Pontiac Trans Am was modified by a company out of Indiana called Auto Forms Engineering, and very few were made, likely owing to the high price of exclusivity. The conversion was sanctioned by GM and you could only order one through your local dealer. This car is one of the few that were made and features a sharp bronze/black color scheme with an automatic transmission and under 40,000 original miles. Find it here on craigslist in Chicago for $14,000. Thanks to Barn Finds reader Pat L. for this find.

Although GM would eventually build its own version of a droptop third-generation Camaro and Firebird, the Autoform work was seemingly done to a high level. Look at that rear decklid with the integrated headrests pods – this was no hack job, which perhaps justifies the cost premium at the time that could add upwards of $14,000 to the sticker price – and that’s in 1985 dollars. This conversion reminds of the work ASC did to transform the middle 80s Celica into one of the more stunning drop-tops available at the time. Of course, they don’t look nearly as good with the top up, but hopefully, you won’t spend too much time driving around with the roof erected.

It’s estimated there were fewer than 250 of these conversions made, with speculation being that the asking price was too high for an option that no one really needs, especially when common sense dictates that a company the size of GM will be able to make its own drop-top in time. The seller’s car is in outstanding condition inside and out, with an unmarked center console, stain-free carpets and door panels, and a crack-free dash. Given the winters in Chicago are fairly brutal, it seems likely this converted Trans Am stayed indoors when the weather got rough. Factory Recaro seats would make this one even better.

The 5.0-liter V8 features functional ram air induction and is paired to an automatic transmission and a limited-slip rear differential. Stopping power is provided by four-wheel disc brakes. The Pontiac also comes with cruise control and air conditioning. The seller doesn’t go into great detail about the company that converted the Trans Am into a drop-top, but I’m sure there’s an aftermarket sunroof historian out there who can help. The original owner of this Trans Am spent all the money and then some to make it his own; now, the next caretaker can get it at a substantial discount while still owning a nearly-new muscle car from the 80s.
