Often a car that's used for bashing has way more run time on it and has been bounced off of everything 10 times, just the way it is. Parts that aren't broken are often well worn.
Like buying a used truck that had a plow on it it's whole life (you have to live in the snow belt to understand) It looks just as good as the other ones with the same mileage but it's a whole different story once you drive it.
