I only ask "what if" because certain racing games (like Gran Turismo) have cars' overall wear-and-tear dependent explicitly on mileage, giving the impression that most age-old cars were garage queens. The Hot Rod games are an excellent example of what I mean, though IMO it would also make sense if the cars you could buy off the street would be a mix of non-running cars, cars held together with duct tape and bailing wire, cars with hackjob repairs, and cars in somewhat decent condition.
