ASM BMW is flat-out outstanding. I came to Alex with a 2016 BMW 340i xDrive for a turbo replacement (Pure800) and an engine tune after another shop had completely screwed up the installation. Alex and his team at ASM really went the extra mile to make sure everything was accomplished correctly, and it's clear that Alex's superior knowledge and experience in the BMW community makes his shop the best around. I’ll definitely be going through ASM for anything I need done in the future. Don't make the mistake of trusting some other random shop, go to ASM and get it done right the first time.
