My '97 BMW E39 got crunched the other day when parked up. Looks like a flat bed truck or whatever hit it - a deep groove in the rear door at handle height. Door still works perfectly, though. Took it in for an insurance estimate, and the garage reckons it will be marginal as to if the car is a write off or not.
I've had it from two years old, am the second owner, 80,000 miles, serviced on the dot regardless, fully loaded and near immaculate apart from the dent.
