My first experience as a customer was booking in for 12:00 mot which I was told I could have done while I waited.
Arrived at 11:50 and was told the tester had just started another mot so I would have to come back in 45 minutes. I don't want to waste an hour and a half on false bookings. Cannot recommend

Penny is an absolute star, so helpful. They were brilliant when both our cars died at the same time and squeezed us in, went above and beyond. Wouldn't go anywhere else now.

I was really hoping this would be my new favourite garage to come to but probably will not visit again, went in for an mot and when it was done, I wasnt rung to be told so, I had to walk in and find out myself, then for my mot retest the same thing but it was ready for over 30minutes, waste of my time waiting, also have asked for a price off a job 3-4 times now and been told Ill get a call or an email and never received anything, maybe they only look for certain customers but I was not treated well, the only good thing was the low labour prices...

BY FAR, THE MOST honest, genuine and fairly priced garage Ive ever had the pleasure of using. The people genuinely try and help you as a person, rather than ripping you off. Have been using for years and will continue to do so. The people are friendly and dont just look at you as another customer, but almost a member of their family.

Not sure what I can say about these guys. Honest and great. They have always given great service. Best recommendation I can give based on my feed back is that my brother is bringing his car up for an not from Bristol.
