My car was at their garage for over 10 days. They could not fix my engine misfire, (the main reason I took my car to them), they are the German Car Specialists. They were recommended by a mechanic from the Halfords Service Centre in Hove. They did however fix my oil leak that I asked them to look at, they also found other faults I was unaware of too. I was billed 1,549.09 which included over 13 hours labour and parts. This was for the investigation of the engine misfire and oil leak. Then the repair to the oil leak and a twisted brake hose! The courtesy car was a 1983 Golf GTI which smelled

First rate, the engineers know what they are doing unlike most garages and they are engineers, not technicians. Priced competitively but more knowledgeable than the competition and they won't rip you off. I went to them with a list of items that I thought needed doing but they decided to check first and found that much of what I'd asked them to do didn't need doing and so they placed the car on the ramp and went through everything with me, showing me what actually did need doing and what didn't and why. They could of just done the work (another garage was going to) but they obviously value honesty

Arranged to give a second opinion on my car troubles at short notice. Quickly diagnosed the problem and arranged to do the work. Impressed they fitted in that day and I had the car back at the end of it. Friendly and good communication.

Be very careful. Told me my service would be around 200 - turned out that was labour only, managed to get the price up to around 550 with products. To clarify, this was things like oil, washer, etc, no parts.
