I don't mean to rain on your parade, but someone should speak on the Germans behalf on a biased non-German forum...

People pay an extra 5 figures because they are ballers. They buy Benzes not to smoke someone in the 1/4 mile, but to show they they are wealthier. That car is his show of wealth. People with those kinds of cars dont care about getting beaten by drag cars and ricers, as those are a waste of attention. They would rather be focusing on getting to their job (that probably pays 6+ figures)in style. Your uncle is probably a very successful man, and he dishes out the extra $ for reputation, not performance.

The class of a Japanese car modded in any way will always be far far FAR behind the class of a German car. I guess you can dream of showing him up, but this is the harsh reality of the situation.
As far as seats go, look into stock RSX leather bucket seats, maybe you can get them retrofitted. They are very nice.
