been looking on some salvage sites, haveny found any 172s yet but found some 2001 1.2 dynamiques and some 1.9 deisels, they go for about £1750 for the whole car, i would imagine 172 stuff is dearer and more popular, thus i cant find any yet! But i dont reckon it would be that much to get just the bits you need, you may have to go and take em out yourself to save yourself some money though. I was thinkin of building a space frame, and sitting an engine in that, doesnt have to be a clio engine, but i could make it look like a clio on the outside. course it would be for track only.
