I've been to several garages in Brighton for MOTs and repairs. And I've had to keep moving on from one to the next because the cost was so high I was beginning to think about giving up driving a car altogether. Most places are either over-priced at best, or a complete rip-off. And I have often come away from garages feeling really cheesed off having been fed nonsense I know to be untrue - just to justify ridiculous prices.
Brighton Tyres & Exhausts are, on the other hand, really good value. Great place for a service and/or an MOT. My search for a decent garage in Brighton that I can trust has finally ended. I shall be sticking with them and would recommend you give them a go.
