They have worked on Mx5's as well as other cars but I have no knowledge/experience in that area with them. From what I've seen with the VW Golf I do say these guys know what they are doing. The man to talk to there is called 'Liam', there's no cowboy hat on this man and they get a Thumbs Up from me

If you own a VW, VW Golf then go to them.
If you own another type of car, then just give them a try, I think you'll be happy with them.
