The 250 GTE has the 3 litre V12, while the 330 America has a 4 litre V12. The 250 GTE was made in approx 950 units, while the 330 America approx 50. Lots of both models were wrecked, converted into GTO, TR,... I think it would be hard to get a 330 America in good condition under 60K. If you would then the 330 America is absolute favourite.
