I'm probably one of the biggest MR2 fans out there, and have owned more than a dozen, and I have to say, for the right one, i'd pay that for it. However, at that price, it better have new belts, hoses, timing belt, fuel pump, plugs, etc. In other words, it better not only have low miles, but better have had a major service to make it road worthy. My experience has been that if you get a car that's rarely been driven, and then start driving it, things start to fail.
The problem with MR2s are, that it's hard to find nice ones. I wish I'd never sold my last one. I've been looking for a replacement for a while now, and everyone I've seen has been a total dog. I don't want to do a resto at all, and most require a total rebuild.
So if the car is in nice shape, original paint, interior, etc., I'd hold out for more money than that too. There are plenty of us old guys that bought them new that now want another one!
