It's easy for me. BMW M6.
First of all, that huge difference in price means something. Since you pay what you get (and vice versa) the M6 being more expensive means it's also better
Simple as that.
Other than that, the M6 has more style, it's much more sophisticated, packed with more technology, better quality plastics and much more comfortable.
NOTE: If you ever get next to a Corvette, just put some force on the rear (plastic) bumper and watch it to distort like it's made of paper. Even in a 8k Daewoo Matiz, such a thing is unacceptable, let out a 100k supercar...
