I restored a 1970 BMW. This shop disassembled the transmission and reassembled it. I asked them to replace seals, fluids and let me know if there were issues. They I paid them to install the transmission as we had issues connecting it to the engine. I was charged about $1500 for the work. We got the engine working a few months ago and took it for a ride. The transmission leaks and the car will not go to second gear. I talked to Bud about it and he refused to work on it or refund money for the work. He blamed it on me and my car for some reason. I paid him what he asked. He told me to sue him if I wanted to get the money back. Worst car repair transaction I have ever experienced.

My step dad recommended I take my truck to Hahn's after I was quoted by a Sacramento shop at $370.00 to replace a part that caused a failed smog check and was quoted $590.00 for a full tune up. Hahn's replaced the part, did the tune-up and oil change, checked brakes and rotated tires for $598.00! Not to mention their front office person Christi was very helpful, friendly, and attentive over the phone. I'm from Sutter Creek, but live in Sacramento and will try to do all my servicing/repairs at Hahn's. I saved over $500.00 dollars taking it here instead of Sac Auto (16th Street) and Hahn's did more than Sac Auto would have. Saved money and got more done! Highly recommend!!

My family has used H&M for almost 40 years. I can call them with my dumb questions, and they have a great sense of humor, appropriately priced and fast! Steve and Robert know their cars and are definitely from the old school crowd of trustworthy, quality mechanics! The only place to take your vehicle in Sacramento and walk away happy!
