I completely trust their diagnostics and am always certain that their pricing accurately reflects the quality service done. 🙂
I was never satisfied with their services. I have low hopes because everyone is always unfriendly.
I was previously told that this place was a little dear, but after using a number of garages in South London, I can state that: a) they are no more expensive than any other garage, and b) they do appear to be the best.
