Actually I will have to agree with you RDMracer. I don't think it's the most beautiful car in the world, but it's pretty darn close.
The Corvette is my favorite car in the world (no surprise there). But, surprise! I don't think it is the most beautiful car in the world. IMO the Alfa Romeo 8C is the most beautiful car ever concieved. There is no way that you can look at it, inside or out, that will reveal any cosmetic flaw. It's amazing.
Other cars i think are beautiful are:
Corvette (any model)
Bugatti Veyron (not for it's speed, I just think it's pretty)
Lamborghini Mercielago
McLaren F1
Spyker (any model)
Alfa Brera
2009 Aston Martin Vantage (V8 or V12)
2009 Cadillac CTS
2008 Cadillac XLR
1984-1986 Ferrari 288 GTO
Ferrari 355 (Spyder, Berlienetta, GTS, I like all of them)
1948 Buick Roadmaster
