hmmm...
do you got a bug yet?
hate to turn someone away but a bug may not be your best choice here. There is much discusion about the abilities of a bug, and high speeds is not one of them.
due to the aerodynamic features of the bug its not much good past 85ish mph. this is becuase of the large amount of lift that the body it self creates. This is not to say that wings and air dams won't help, but this car probably wont handle like one you may hope.
if it a project your looking after, a bug is a good place to start. But please don't expect "lotus handling" in one of these things. Have you thought about a Lotus 7 or perhaps a corvette?
although there is nothing like pulling away from somone in a bug
