Gullwing America, a company specializing in turning modern Mercedes cars into retro-looking hot rods, reveals details of their their latest project: the GWA 300 SLC. The car is based on a brand-new SLS Roadster AMG, and it’s being converted to look like a 1955 Mercedes 300 SC W188.

This one-off model, built for an Eastern European customer, features a bespoke handmade aluminum body, and custom-made wheels. The running gear and interior are pretty much stock SLS.

It has been a challenge, of course, to fit the SLS with the new outfit. For instance, they had to change the position of the pop-up rear spoiler, and do a lot of structural work to make those wheels fit and that headlights work. The end result though is a pretty exquisite thing. The SLC features the standard fabric rood, plus a new removable hard top.

The wheels are GWA Evolution models, size 22 x 12 rear and 21 x 9.5 front, wrapped with Continental tires. GWA also provides the car with a special exhaust system and height adjustable suspension.

No word on the pricing, but rest assured such a treatment is hugely expensive; something in the neighborhood of half a million dollars, we reckon.
