I found this on bringatrailer.com this morning and now I really want find an old Mercedes Benz.
This 190E 2.5-16 Evo 1 is pretty awesome, 1). Because its rare and 2). because its built for the track, and the owner obviously did not cut any corners.
Caged interior with Recaro seats, deleted rear seats, 6-point belts, upgraded suspension and brakes.
It even has a glass breaking hammer!
Why is it cool? Because this Mercedes has a DTM spec 2.5L Cosworth engine, the only part that sucks is that was never sold in the US, so finding one locally/regionally/nationally.. is impossible.
