Things I made dealer fix: 1. read end whine at 20,000 (dealer fixed) 2. no idle 40,000( IAC cleaned out, fine now) 3. rear end whine came back 50,000 (dealer fixed, don't think they fixed it right the first time, a lot better now) 4. Coolant light comes on started at 50,000 brought to dealer at 60,000 (just a bad float, dealer replaced tank under ESP) The above issues besides the rear end, I consider minor. the below small issues that are just part of owning a mustang, I think. Chirping throw out bearing. idle can get lumpy at times depending on weather and humidity. AC compressor messes with the idle too much. (usually have AC off though) this may seem like a lot, but we treat these cars like babies. I am actually quite happy with it.
