Your right, a few years back Sapphire Cosworths were being sold for less than 3k but they were the roughest ones around,mostly rusty with worn out seats, worn out engines and gearboxes etc A lot have been broken up and thankfully now, good examples are starting to get harder to find and so the prices are going up. There are fewer Sapphires now than 3 doors so if your friend wants a really good example he will have to pay quite a lot for it.
