I am looking to repair my car by trying to find cheap parts formy lexus which has been damaged. The parts I'm looking for are:

Radiator
Boot Lid
Bumper
Back Lights
Rear Panel

Will appreciate if anyone knows any sites or contacts where this can be purchased from.

Thanks

Try ebay or www.car-part.com Those are usually good starting points.

If you're in the UK (which I'm thinking you might be based on calling the trunk a "boot lid"), then I am not sure outside of Ebay.
