I could never choose ONE car, there are too many different beautiful cars all in their own different ways. One that pops to mind and has always been in my top ten is this, the Panoz GTR-1.
^^Thats my vote. that car is so breathtaking in person.
yeah I can't believe it took 6 pages to get to the Lamorghini Miura. Most beautiful car ever and the first supercar ever....
Alfa 8C Competizione. This is ART.
