I have the opportunity to buy a 525i, one owner, 23,000 miles with a clean Carfax report for 15,000.00. I test drove it, body and interior are like new. I did a little research online, and other than routine maintenance, they seem to be relatively inexpensive to maintain. I have a 2000 Lexus with 75,000 miles, that has never needed any major repairs. Would you recommend the used BMW. or should I look for a newer Lexus?
