While on a business trip, passing through the Livermore Valley on a Friday, my BMW 650i overheated, losing all its coolant. Kahlers got me on the road home before the end of the business day! Kahlers trouble-shot, finding multiple cooling system issues, including the water pump after the second test ride. A "quick fix" of the initial coolant loss issue would have put me on the road, but Kahlers made sure the job was done right ... finding the water pump still was an additional issue. Kahlers got the job done... RIGHT & in time to get me on the road home for the weekend.
