I have been using this shop for over 5 years. They are very knowledgeable, trustworthy, fair, and clear. He has experience in many European auto makes. Highly recommend without reservation. Service: Air conditioning

Took my 'new to me' Ford Raptor there for an oil change/tire rotation and general inspection. They were extremely prompt, thorough, and walked me through some general concerns and kept me informed every step of the way. They're true professionals and I love their notification system and how organized everything is. Will be going back as well as recommending them to family members and friends.

Wanted to update this review to add further accolades! The team there is sooo great. They are truly the definition of what a small business with the the customer as the focal point, should be. How often do you have someone from and auto service company hand deliver a "thank you just being a customer" gift to your home. It's a little thing, but also a big thing, that is missing from today's companies and business that we all use.and has been for decades. Really nice.very surprising. Oh, by the way they also do great work as well! Vehicle: Range Rover Great group of guys. Straight to the point. Very knowledgeable. Thanks for the GS cookies! Cheers

Very happy with both the customer service and the auto service. Would highly recommend. Had the MB Service B performed and also replace the battery on a 2015 ML350. Got a ride from and to the shop - thanks Jacob and Jason. Services: Battery, Oil change

After going to a different local mechanic for years only to find that they have been dishonest and performing unnecessary work, I was referred to HM by a family friend. Needless to say I have been blown away by their professionalism, honesty and friendliness. You walk in there and you just feel at ease with their friendly staff. After a couple experiences with them I have permanently moved my cars to HM for any and all service.

They are honest with concerns and give you a detailed explanation of what may be needed or if it something that may be of future concern and how much it will cost with a reasonable price instead of saying it needs to be handled right away and then over charging you for the service compared to my experiences elsewhere. I truly do appreciate the service, knowledge, and friendliness of HM!

I brought my car to HW Motor Works for inspection. The shop was clean and very efficient. I was in and out within 30 minutes. Jason was super friendly and he's enthusiastic in answering my questions. I'd definitely bring my car back if it needs service. Btw, two side benefits of bringing your car here: 1. Most likely you'll catch a glimpse of some rare cars- I caught a Lamborghini. 2. The shop is in a quiet closed loop with gentle incline/decline- you can stroll around while you wait for your car.

My alternator died on my C300. Jason had me drop off the car same day and it was fixed very quickly. They do great work and very pleasant to work with. I also had them change my oil out as well as some diagnostic work and a quick inspection of the car Services: Auto engine diagnostic, Oil change
