ive driven quite a few cars that have been previously written off......and with differing quality on the work....but even the ones that have been done perfectly......still feels as tho theres summat not quite rite....n thats without even knowing its been written off...so not a biased account......yeah they may look like they in factory condition, but a bent then re-bent into shape piece of metal is always weaker than a non bent bit, even with stregnthening (which is a dead giveaway) the paintwork is easy to get looking as good as new for someone thats handy with a spray gun, and a lot of things can be hidden underneath the paint
