It's not just rarity, it's the part in history when rallying was at it's most extreme, if you wanted to buy a modern rally car you'd be looking at more than £60k. These cars and also the integrales were the last generation of cars that relied on mechanics instead of software engineers and electronics experts and that's why i think motoring enthusiasts love them. Have you seen the lines that modern WRC's take through corners, they are vertually using traditional racing lines because the cars are so good at finding traction and keeping the car under control the art of sideways driving is going out of favour and it's a sad trend i'm affraid that isn't going to turn around.
