Our Reviews
My appointment was scheduled quickly when the part for my recall issue was received. Everyone from the greeter when I arrived to my review of what was done was courteous and made sure all my questions were answered.
Oil change was easy to schedule and was able to get in on short notice. Service was fast and car was was a bonus.
I wasn't informed about the diagnostic cost til 3 hours of me sitting there with no updates THEN dudes came in (1 cust 1 sales guy) and changed the channel while I was watching...I clearly didnt matter as the guy mumbled about the view...seriously, cause there was women, racial or???? Just a handmaids tale of a moment. I was trying to get work done on existing vehicle as im ready to trade and buy new...it will NOT be Boucher...im good!
