As a girl who knows nothing about cars I struggle going to garages. I called up STG and they were very welcoming, they put my car up on the ramp and checked everything. They weren’t pushy and I got what I needed done on the same day. Highly recommend this place.

I had booked my MOT in Halfords, however when I came there their compressor was broken and they couldn’t lift my car so I had to find another garage urgently as my MOT had already been expired.
Many thanks to STG St Dunstans Garage personnel who agreed to carry out the MOT for my car in the same evening. I really appreciate it. Good luck with your business!

I’m new to the area and was yet to find a reliable mechanic. Needed a last minute MOT on my Corsa a couple of months ago. The guys at STG were really helpful and managed to squeeze me in. It passed with a couple of advisories, one of which they sorted out for free before I picked my car up. Great lads and great service. Highly recommend STG
