Kaizer is a little way out of london yes but you get there on main roads and dont have to mess with london traffic. i wont be going anywhere else thats for sure and its about an hours drive for me.. he knows his stuff, is very friendly, has good coffee, Wifi and is very reasonably priced. having watched him set my car up on his hunter system he certainly didnt just spend time getting it into the green lines and the difference it has made to the feel of the car is amazing
