Where's the front of the frame horns? I'm assuming the sheetmetal was patched up. Definitely some nice parts and that rear bumper appears to fit pretty well.

I would be a little skeptical,or maybe a lot skeptical. The car was complete,and looks to have been painted recently,but is now apart. There could also be a lot of bodywork hiding under that paint. Maybe done right,maybe not.
