Reading Jalopnik as I usually do, I came across an article about expensive cars "ruined" by tuners. Not just the performance, but mostly the appearance as well. In the comments (thank you "Kotaku Fix" plugin for fixing the comment system!), someone posted a whole website about uglyfied luxary cars.
You could just enjoy your Mercedes Benz coupe, or you could spend 3x the purchase price getting it guilded in gold, repulsive bodywork, and atrocious interior, and stacked with a Clarion G80 stereo (the sign you've "arrived" in the 80s):
