I have a 1995 BMW 840 that I am planning to sell, but it needs mechanical work on the ASC & Antilock braking system. This a minimum $4,000 repair at a dealer so I am looking for another option. Does anyone know a reputable mechanic in the Chicago area? Preferrably the repair shop would be in the western suburbs, but anywhere else in the area is fine as long as you have had a positive experience.
