While I agree there is no substitute for cubic inches, there are some exceptions that hit the nail on the head. I used to drive a '76 Datsun 280Z, that was one fun car, loved running at 85-90 MPH all day with 160,000 miles on it. Now about Audis, I have a '98 A4 Quattro, 22 years after the Datsun 2 seater was built, a 4 door sedan has almost idential performance at a reasonable price.
I do agree that when it comes to ultimate convertables it is hard to beat old American iron when you take everything into account.
I'll put my 2002 Honda S2000 up against any piece of V8 iron ya got!
With 240 horses pounding out of a 2000 cc engine, it is the most efficient production engine ever offered. When you climb on her, at 6000rpm she kicks in her second chain drive cam, snaps your head into the headrest on her way to redline at 8,900 rpm, to the quarter mile at 115mph. Tested to be the stickiest car in a slalom other than a $400,000 Lambrogini. Four coils feeding spark to carbon fiber infused aluminum pistons, driven through six short throw gears.
An unbelievable car for $33k.
