I have for sale a 2005 525i which I bought as a CPO. The CPO warranty and maintenance coverage ended in December. All maintenance work has been done at the BMW dealer and I will provide paperwork with the vehicle. I have had no problems since I bought the car at 45k miles 3 years ago. The only work that has been done other than routine maintenance was recall work for the passenger seat airbag sensor. The car runs perfectly and I have been completely satisfied with it. One of the air conditioner buttons has a small chip in it, there are two dime-sized dents in the gas door and one two-inch dent in the passenger door. Options are listed below, feel free to contact me for further questions.

Here are the blue book values for "Good" condition. My price is slightly higher than the average private party value for these sites primarily because my car falls between "Good" and "Excellent" condition and the price reflects that average.

Edmunds Private Party Value: $16,520
KBB Private Party Value: $15,315
