I was in a hotel car park and stupidly took a right turn too early and mounted a kerb made of cobble lock. I heard a loud crunching sound and stopped. Got out and looked underneath and my e220 estate was wedged on the kerb underneath. Eventually I managed to drive over the kerb but a piece of flat black plastic came away from under the car. What have I done ? Car is driving ok. Dreading visit to mechanic. Sorry didnt know where to post this.
