Hmm some of the coolest cars ever came in UGLY packages. Try the RS200. The evolution model held the record for fastest production car 0-60 for years and may still for all I know. Its still UGLY. How about the Pug 205 Turbo 16? UGLY but cool. The Nissan Pulsar is long on ugly, but still cool.
Also anything that makes a car less noticable to cops/theves/riceboys/insurace companies is a good thing. So if no morons buy it because it looks cool, we will all benifit from less hassle by the police, a better owner rep, and the insurance companies will have less boneheads racking up numbers in the claim statistics.
