How would you like to make a ton of money, courtesy of PistonJuice. Yes? OK then, do whatever you need to do to buy this car then mothball it for a year or two. Bingo. This is a 1 of 500 made Nismo Edition GT-R R32 (not including the 60 race cars) and has a warranted mileage of 16,500km (10,250 miles) with full service history. The car is presented in as-new condition, down to the unused spare wheel and is part of a private collection. Make that call, this is very much a car on the rise among collectors that can appreciate Japanese classics.

Price: $64,990 (£47,400)
