Been there thrice. They even picked my car up following a MOT failure due to worn/faulty ARB/bush, changed the ARB, got it through MOT and dropped it back. Was quite satisfied with their service.
You don't get anything near a 'dealership treatment' with them. But they are good at what they should be doing, that's been my experience.
Also been to W.D.M Cars and MSL Birmingham. All of these guys are good. I prefer the last two as the 'customer experience' seemed much better.
