I'm not really a 'car guy' so I can't say what current car would be best for KITT.
But off the top of my head, I think a Corvette would have been a better choice.
I'm a car guy!
But I don't care at all for the new look on the Corvette. It looks too much like any other Japanese car... which is not a bad thing, in itself.. but Corvette has now lost that unique look it had up until just a couple of years ago.
Now, if KITT were a 1996 red Corvette.. or, an orbit orange 1969 GTO Judge.. or, a dark red 1969 Mach 1 Cobra Jet engine Mustang.. or even a black 1971 Plymouth GTX..
