This 1991 BMW M5 (chassis WBSHD9316MBK06104) has 110k miles and has been a local Bay Area car since new. The seller says it has been a 1-owner car, and we like that it retains its original functional turbine wheels. Find it here on Craigslist in Palo Alto, California for $15k. Special thanks to BaT reader Dan W. for this submission!
