Ferrari 275 GTB 4 S N.A.R.T. Spider – just 10 special North American Racing Team versions of the 275 GTB 4 Spyder were produced in the late-1960s. Ferrari dealer and NART boss Luigi Chinetti ordered the cars, buying each for $8,000. Unfortunately, low sales meant that 15 further orders from Chinetti were cancelled, but that makes their value in the present day unbelievable.

This particular car was owned by Steve McQueen. The king of cool’s name on the log book certainly didn’t harm the value, either.
