Unplanned test of rear bumper yesterday as I stupidly reversed into a woman in an old civic in a petrol station. Looked bad when the cars were 'getting intimate'. Large dent looked likely. But when uncoupled absolutely no damage, no dent, just a small amount of paint missing (hardly noticeable on the grey). So, test at low impact speed = success for bumper. The woman had a couple of scuffs on her front bumper (rubbed out straight away)but initiallyyoud have thought she'd been shot!! Nice touch though, she became very concerned about my 'gorgeous car' and even suggested I'd done it on purpose to chat her up!
