They have been in business for a long time so they cant be that bad. Like many car dealers, they have some good ones and some not so good. If its too expensive in your opinion or not what your looking for, then dont buy it. Simple really. If any place had 5 or 6 cosworths in you can bet that one or two would not be 100% of course so i dont see the problem. Im pretty sure they sell some cars on behalf of the owners too, so that may explain some being a tad expensive as obviously they have to add there bit on to cover a warrenty, any prep work needed and other costs.

Go and take a look mate and judge them for yourself instead of going by some peoples opinions (many of which ahve probably never been) and if you dont like them then look at some others, if you do like one, then buy it.
