I went with sky after recently having my insurance cancelled trying to add on springs, tints, k&n, this was with Esure, who let me add Mountune to mk 7 three years previously, but as 140 wasnt on their insurance system I had to add it all seperate and didnt even add anything to my premium!

I had bad power loss on the Mk 7, would pull and and the car would just die on me :-(
