It's a big part of why I went with the C3 with swap and goodies. Almost nobody has any idea how fast I really am since I look pretty stock, though a few imports found out thinking they were picking on a slow domestic.
Throw in the excitement of 60s suspension geometry (even thought it's all freshened up and hardened) and it's a hoot to drive.
About the only bone stock car (within reason for me) I'd be interested in as an all arounder would be a Turbo Porsche. Other than that, I'd rather build a Factory Five Kit or a whole host of other more interesting things.
