I have been having my E53 X5 3.0i serviced at Premier Autowerks for almost the past two years, and the service is always top notch. Jim and Emily give you personalized attention, they communicate frequently, and the prices are competitive compared to a dealer; the closest is in Rockville as it is. They do not just do BMWs. I recently acquired a new-to-me 987.1 Porsche Boxster S, and Jim did not hesitate to offer a bore-scope service, given this known issue with that type of car. I won't name names, but not even a local Porsche specialist was confident in performing this check. When that was completed, Jim was able to provide picture evidence that everything was in order. They also performed a full inspection and informed me of issues that had to be addressed. The work is fantastic, and I love how we have a European car specialist right here in Frederick. After hours pickup is also very convenient.
