150,000 miles in my daily, tdci zs fiesta, and only major fault so far was an egr valve at around 80,000. Had my R35 for 18 months and didn't put a foot wrong. Purchased a new 123d convertible for the other half and done more miles going to and from BMW than she done for fun so swapped it for a JCW roadster mini and low and behold its sitting at BM now for warranty work.
