About 18 months ago we bought two Certified Pre-owned 2007 BMW 530i, automatic, from Vista BMW in south Florida. One gray and the other one (mine) in black. The gray one still have an excellent paint but as you see in the pix below my black car paint is fading. I've seen another 5 series black car with the same problem and another 7 series as well. One friend who works for BMW dealer told me that BMW knows about the problem but they don't want to admit it so they don't loose money on a recall.
BMW North America and Vista refused to fix the paint on it. I've been looking around for paint shops and got some quotations ranging from $800 to $4000 for fixing it.
