I guess if they really do fix it like new and give you a great deal go for it
I tend to inspect things basiclly by nature and also for a living so my advice if you decide to move forward with it, when you go to look at it again take a flashlight and have them put it up on a lift so you can inspect it yourself very closely if you see any scratches or marks under the body anyhwere then it is not "like new" and this gives you even more bargening power. also as already mentioned ask for the invoice of the repairs you should see minimum quarter panel, rotor, knuckle, lower valence, maybe a running board. the door could have been pinched when it was opened after the accident that is likely repairable. Inspect the drivers side upper pillar very close run your hand over it as any bending may not be visible to the eye, check all the alignments of the front end clip (both sides) and hood
