Don't waste your time or money on these con artists. Took my car for an MOT and had it aborted in the first 5 minutes after claiming my car had a dangerous level of oil in it and that the head gasket was going (I've had the car 2 years and have never touched the oil or had any problems with this before or at previous MOTs) then claimed it would be several hundred pounds to get this fixed. Took it round the corner to AD's autos and they dropped the oil level and did the MOT and low and behold, my head gasket was completely fine and my car passed the MOT
