Well, my friend has the Diablo that I hit 215 in and the top speed of those is just barely 220, so there must be mods that he did to get that up to those speeds. Then definitely don't come stock being able to do those speeds. As far as that Corvette, well damn. I love Corvettes. I remember last year reading a Road and Track article on how they got permission from the Navy and raced a fighter jet in 0-60 and 1/4 miles with a twin turbo modded Corvette C5 and they ended up out-speeding the jet in a few runs.
