IMO the porche's best feature is that it's too fast for people to see how damn ugly it is.
I'm not a big fan of Corvettes either. Too many yuppies driving them as a status symbol. Now if someone takes one and builds it up into a nasty ass street car then that's a different thing entirely.
On top of that my opinions of the viper are pretty similar. Terrible drivability+ho-hum astetics*bruteforce engine power="meh" they just don't do it for me. YAY we put a 500hp truck engine into a miata...um yea of course it's fast? Do we want to drive it everyday HELL NO!
