 Trustindex verifies that the original source of the review is Google. After 20 years of driving, this has been one of the best experiences I’ve ever had with a car garage – Treeton Auto Services truly stands out! 😁

If anything car-related feels overwhelming, this is definitely the place to go. They immediately put you at ease and deliver top-quality work. The front-of-house staff are fantastic – professional, polite, and efficient.

And the mechanics? They handle all the tough work behind the scenes, and I really appreciate everything ypu have done for my car so far! 😁

I had my timing chain replaced here after five other garages either couldn’t be bothered or didn’t have the right tools. That alone says a lot.

Their invoice system for quotes and payments is smooth and easy to use. The only small hiccup – if you’re paying by card, just hope the machine is plugged in! Jokes aside... it works if you dont go in too early 🤣

A big thank you to everyone I’ve dealt with. I’ll definitely be back (hopefully not too soon though! 🤑).  Defo found the pot of gold at the end of that rainbow (see picture) Great garage!!

 Trustindex verifies that the original source of the review is Google. I've used this garage for just over a year and a half and every time they are absolutely amazing. I've got a relatively old car so it's always running into problems, and it's always quickly resolved with quality repairs from here. Customer service is also great, Gavin deals with me most often and he's always been extremely helpful.

 Trustindex verifies that the original source of the review is Google. Have used several garages over the years to keep 4/5 work vehicles on the road. These guys always seem to come though. Glen on reception is a great guy, a very ‘can do’ attitude.

Helped us out no end, with the latest issue being a work van showing problems on the 19th December and then back on the road for the 5th Jan.

A good professional outfit that still have that local garage feel.

Thanks, Chris

 Trustindex verifies that the original source of the review is Google. Treeton Auto Services helped me with my van today and I think the service was fairly fantastic.  Not only do they have a comfy and clean reception area, but also a large and well kept garage area that looks a lot more professional than a lot of garages out there.

I was also impressed that the staff kept me up to date about what was happening with my van.  During my visit about 5 other customers came in to drop off or pick up cars and they all seemed happy.

I even got a free coffee and ginger biscuit.  Would certainly recommend giving them a try.  Parts were also ordered fast and all work double checked.

Thanks guys!
