1991 BMW 3-Series IS

Additional Info:

Selling my very special 1991 BMW 318is. This is a Canadian-market car finished in Sterling Silver Metallic over a black sport interior. It was imported into the United States in 2016, and I purchased it in 2017.
The car was thoughtfully developed into a naturally aspirated, high-revving driver’s E30 while retaining a clean and period-correct appearance.

This is a properly developed and distinctive E30 that looks largely period-correct but provides a much more engaging driving experience than a stock 318is. Please contact me with serious questions or to arrange an in-person inspection in San Mateo.
