But let's not forget about more modern Ferraris. Here we have a 1985 Ferrari 288 GTO, and it went for $2,365,000. Bonhams wrote: 'The last few years have seen the 288 GTO rightfully assume its status as a truly collectible icon, by merit of its modest production, iconic design and blistering performance.' According to the auction house, only 36 of these cars can be found in the US.

A similarly styled car to the 288, this 1987 328 GTS went for $82,500. That's a massive bargain, by the standards of collectible cars from the Prancing Stallion.
