I was rear-end twice in two consecutive Audi 80s, so you have my sympathies. I've had a 2003 4/4, zetec black top for about 10 months and the only issues so far were seized rear brake cylinders (probably something to do with the previous owner storing the car rather than driving it) and a failed brake light switch. I love the car and am happy with a small-engine Mog.
