Auto repair service near Thornton, CO

They kept my car a total of seven days. I had to keep taking it back so they could guess at what was causing the check engine light to glow, all the while charging me 95.00 an hour plus parts I didn't need. The rough idle problem was never fixed. All of this for a whopping 1200.00.

My Audi had an issue with intermittently not starting. Bill checked out all the possibilities. And he went beyond using his deep knowledge and experience to find the problem. He found and ordered the part. And I am thankful for the loaner car. He and his team do an excellent job, know mechanics and work to correct all the problems. They are very customer oriented and a pleasure to do business with. I highly recommend Slipstream Autocare. Jan Kirk

Jeff's taken great care of my Jeep Grand Cherokee for years and has kept my Ford Escape going nicely for more than a decade. His work is good and the pricing is fair. I wouldn't think of taking my cars anywhere else, and recommend this garage without reservation.

Unimpressed to say the least. Typical sleazy used car dealer. Wouldn't even attempt to connect me with someone to give me a trade-in value - just asked me what car I wanted to buy and bragged about how long he'd been in business. If there was a zero-star rating, I'd give that.

Lazy staff. Business doesn’t return customer phone calls. Poorly managed. Only want to work with wealthy Boulder customers. Go anywhere else. I didn’t want to give this review any stars but the site required at least one star.
