They really are overpriced for what they are. Unfortunatley being a cult car doesnt mean its a good car, like the beetle mentioned earlier. The ae86 and the Mk1 mr2 have basically the same mechanics, the MR2 is faster and has better handling ie it would lap a track faster than an ae86 but the ae is worth 4 times as much.
They rust faster than a really quick rusting thing and were outdated when released by being rwd compared to everything else at the time. Now days you youngsters think rwd is "FTW" but if you were brought up driving rwd then you know that fwd is much better 99.9% of the time.
Also when you see cars like this that when I started driving were about £300 and no body would touch its amazing that people can all of a sudden think they are amazing.
Just my point of view of course and would be intrested in other peoples.
