Very upset ,that I had to drive there so early, and then was told it would not be looked at that day. So I made another appointment for June 24th and we took it in Monday evening (June22 ) so there was no issue with time . And then was told they didn’t find anything wrong , so I took my car home !

This is the only place I want to take my truck for any kind of service. Years ago people always said don't take your car to a dealership for service it's too expensive but I have a good peace of mind when kind of service.

I definitely had a less than desirable experience on this particular repair. From being told that a loaner being available was not how they schedule service, having a coupon from my last oil change that I wa particular repair. From being told that a loaner being available was not how they schedule service, having a coupon from my last oil change that I was told was for my next service…which should have been this one…, all the way to approving an estimated repair of $402, then being told my total was $535. The cashier was very rude about it, however, they did fix my total and I paid $402 in the end. But for Mark Allan to say that women should feel comfortable coming to their shop. I think he would be very surprised at the way women are treated. More
