Just been to a garage to buy some new tyres, but when i was leaving i reversed back and reversed off a ledge couldn't see it in my mirrors as it was so low! There was a massive thud and now my car has a vile loud vibration comin from under the gearbox!! When i hit the floor it pushed the exhaust system forward and bent the cat pipe from the manifold (well i think so anyway). Is there anything else that could be causing the vibration???? I'm totally gutted, this just happend about 10 minutes ago:dead:
