Mike was great and articulate. I took my 1997 landcruiser to get a tune up done and that he did. Spark plugs, wires, distributer cap, alternator and starter to name a few. Service was quick and on point. Thanks for taking care of me.

I’ve had several visits to this shop and I’m always happy with the service. Mike is an honest business owner that cares about his customers. He is very communicative and takes time to answer questions and concerns. He has always followed up with me in a timely manner. The last time I was in he identified some additional small repairs and let me choose if I wanted to have them fixed. I also feel that his prices are very fair. I drive far out of my way to visit his shop because it is hard to find a good mechanic. I’m very happy to have found him!

I had a great experience using this business for car issues today. Mike was very knowledgeable and friendly. I felt like I could trust what he said and will definitely be a return customer for any future car issues!

Great shop to get your mechanic work done. Honest guys, won't rip you off, hard working, and they do the job expediently. Took my Toyota Land Cruiser with a not so easy job here to do.

Fixed my car for a good price. Didn't try to upsell things I didn't need. Respectful. Was honest. I do plan on coming back everytime I need to fix something on my car or my wife's.

Great service overall, was fair with pricing, with relatively quick completion. I appreciate that Mike took the time to explain what's going on, what my options are, and did not push for unnecessary repairs. Would go back in again.

I’m honestly amazed I haven’t posted a glowing review until now! Having a kind mechanic that you can trust is honestly invaluable to me. They’ve gone above and beyond to help me SO MANY times. Not only does Mike do excellent work, he is a lovely, caring person who makes an effort to help you understand what is going on and make an informed decision when deciding what will be done. Growing up my father instilled in me a healthy wariness when getting my car serviced and drilled it into my head to always be accompanied by a man as to not get taken advantage of- which is kind of an awful idea at its core and hopefully an outdated way of looking at things but absolutely understandable to me. That being said, he is the first mechanic I’ve felt so trusting of that I don’t feel the need to be escorted by someone. Mike has never made me feel like he wasn’t giving me a fair shake- on the contrary really- he’s so thoughtful and honest that I try to sneak a tip to him every time I go and if he catches me he won’t take it:) I just cannot overstate how thankful I am I found this shop and how well I’ve been taken care of there. They’re highly skilled, efficient, honest, expedient, considerate and just a wonderful blessing and godsend. If I had one complaint, it would be that they finished working on my car the other day before I could bake em cookies for bein the best. Couldn’t possibly sing their praises enough.

Mike is a great guy to work with with very reasonable prices. Even gave me things to check over the phone before bringing it in. Best mechanic in Denton!! I won't take my car anywhere else.

Feb 06, 2024

Mike is awesome. Definitely recommended!!

Feb 06, 2024

The guy you want to call and talk to. Mike and his guys are the people you want to bring your business to. In and out with no problems and communication that far exceeded my expectations. Never had to do service on any of my cars besides going to a dealership, my lady put the car through the ringer and Mike gave it back to me in brand new condition. I was referred here because of the honest work he does, and I will do the same to any Denton/Lewisville native. Thank you

This is the best mechanic in denton hands down. Mike has awesome Coustumer service. My car is a handful and a lot of work and he's been keeping me updated every step of the way, and won't give it back until he knows it's working good. Thank you Mike for all your hard work. I recommend him to everyone I run into.

Amazing experience! It’s hard to find a good, reliable mechanic that won’t rip you off as a young woman. Mike was very kind and even took me to work in the morning because I had to leave my car at the shop. Service was fast and simple. This place is going to be my go to the next time I need maintenance/ repairs on my car. If you are thinking about coming here, I can say without a doubt you won’t regret it! Thanks, Mike!
