Audi's first true sports car: Grrrr8!

The R8 is also - surprise, surprise, for such a high-tech company - 100 percent hand-built; 75 percent of the body is handmade, and it is assembled at Audi's Neckarsulm factory. There are 325 feet of hand-done welds on the aluminum frame, and the entire engine bay (open for viewing like the Ferrari F430) is swathed in carbon fiber and lit at night like a fine sculpture. Frankly, given the high level of craftsmanship, it's surprising that Audi doesn't charge more than $115,000.
