"Excellent Service! I took my car to them for a full transmission fluid flush and refill, brake fluid full flush and replace, and an oil change. These are Good People. They do Great Work for a Fraction of the Price the Dealership wanted to charge me. They are now my go to shop." says Mike on Google

We treat every vehicle — and every customer — with care and respect. Serving the Missoula, MT community with complete auto care you can count on.

You shouldn't have to stress about whether your mechanic is being straight with you. We believe you deserve better than that.

We agreed that I would drive my car a little longer and see if it gets worse. He used suspension ears and spent a lot of time trying to diagnose my car. Many shops would’ve just told me I needed struts and would’ve charged.." says Tony on Google
