Okay,
Revs most of the time is USELESS if they smash and fix up the car themselves.

Make sure all the factory standards are suppose to be there.
Eg. Brake pads are the correct colour, Strut bars in the right place etc.

And ESPECIALLY the panels are aligned correctly (Could signify its been smashed) and the colours are blending in correctly in the sun/shade etc.

Check the Lugnuts are the correct size for the wheels. (Mismatch lugnuts = fail)

My 2 cents.
