So some chump drove into the back of my Focus (hatchback) in the summer at a roundabout. He can't have been going faster than 10 - 15 mph but it shunted my car forward slightly. At the time I thought my car was ok having been protected by the towbar but when I got home the boot was very difficult to open. I took it to a garage and was told there was nothing wrong with it so I left it for a while. But since then it has never quite closed as well as it used to (the boot catches sometimes and doesn't shut properly) and it now rattles horribly over bumpy surfaces. Does anybody know if there is a fix for this?
