There is no prevention. I got my car for about 2 months, parked
in a multi story car park, with 2 empty lots on my right. Lo,
someone reversed into my right side of the car, crush the right
side panel and scratch and dent the bumper and cracked the
headlamp. of cause its a hit and run case, discovered it when
returning my car. The repairs came to about 1.3K ..... Now,
whatever it is, maybe mine is a very unfortunate case, i try not to
let this case it eat into me and carry on driving happily, its a
choice, definately got heart pain lah... anyway you can't prevent
everything.
