First up, let's take a look at this crazy looking Bentley which tosses aside the normal air of sophistication for a brutal Chevy 502 cubic inch big block V8 that is supercharged to produce 675 horsepower. Interestingly enough, Bentley cut its teeth with racing cars early in the 1920s and 1930s with multiple 1st place finishes at LeMans, but went on suspended hiatus until it return to sports car racing in 2001. It won't win any awards for fuel economy, but this thing should provide an excellent value in smiles per mile.
The next car in this competition is a kit car that uses a basic Datsun 240Z chassis and turns the volume up to 11 with a Chevrolet 350 cubic inch V8 and manual gearbox. It does a pretty good job of looking like a Ferrari compared to many kits, and the Z chassis isn't a bad place to start for handling. With cheap Corvette power it could very well go and turn better than a real 250 GTO for a fraction of the cost.
