 Trustindex verifies that the original source of the review is Google. I got a very quick inspection on a Sunday morning by an slexceptionally kind fellow. He determined the flat tire could not be repaired and swapped the spare, and I got the tire replaced in a few days. Great experience overall.

 Trustindex verifies that the original source of the review is Google. Sent my car in a for a day to fix timing belt and other maintenance requirements at 160,000km -- they did a fast job, and communication was excellent as they flagged other optional issues during the service call. 10/10 would recommend

 Trustindex verifies that the original source of the review is Google. They came to my house and did everything they were supposed to at agreed price. Much better than sitting in dealership or tire shop. Have my tires in the winter storage and will call again each season for swap. Pretty easy.

 Trustindex verifies that the original source of the review is Google. We've just purchased new tires from Changes on the Fly and had them installed & balanced this morning in our driveway.  Their technician, Jerry, arrived on time, was very friendly and had the job done in an hour - we didn't even have to come outside!  Prices were also cheaper than quoted at a local shop, despite doing all this in our driveway.  Amazing.  Call out to Jerry and Daniel (owner?) for 10/10 customer service.  We'll be seeing you again!

 Trustindex verifies that the original source of the review is Google. Really quick turnaround on tires for my Explorer, where some other dealers were unable to find the OEMs I need, before returning this leased vehicle.  Very reasonable pricing, especially considering they do this all in your driveway.  Most of all, the service and positive energy this team has, was tremendous.  That was highlight, for sure.  Thanks team!  Will recommend you all to our neighbors!

 Trustindex verifies that the original source of the review is Google. Very Accommodating to Film and Television Productions.  The Technician that they sent out to service our vehicles is named Darnell.  He knew ahead of time what make and model of vehicle that he would be working on. He had everything prepared ahead of time for each vehicle before he called you in. He was also very professional and friendly. Highly recommended!!!
