Buying an accident damaged car will take a big hit from your bank account, however in the long run it will probably be cheaper and a lot less hassle to do it this way. And when your finished with it you can sell on any parts you dont need.

I think you will be surprised just how many little niff naff things you will need and that will end up costing the earth to buy seperately!

If you do buy the full car then you can swap over the engine bay and interior loom, and it will all go in with no custom parts, as the bodyshells are the same apart from the wider wings
