A "pleasant original deluxe-sportster, stiring the blood of every real man"

Autoblog:

ATT-TEC has been busy this end of the year, and here they are presenting yet another softly tuned German car, this time an E Class sedan. Called "a car of extra class – no doubt!" and "flawless everywhere," it wears a comprehensive aero kit and 20-inch wheels. Intriguingly, it also sports a round void where the grille emblem once lived, and a matching void in the vents aft the front wheels.

ATT didn't mention the engine at all, so we figure they left it alone. The remaining mods will run you €10,321 ($14,757 U.S.)...

No engine mods? What kind of operation are these guys running?
