Good indie wit STAR in London?
 

Hi guys, bought a 2000 E280 Avantgarde about 2weeks ago, and its giving wierd malfunctions (funnily enough, the reason i sold my E36 BMW and bought a merc).
Everyone's said to get a STAR reading first. However having paid fee's for a gas course, buying he car, and not having sold another of my old cars yet, im not willing to pay the £100-odd that MB are asking, just to find out what the fault is/faults are.
So does anyone know a good indie in or around london (preferably close to SW London-i.e. near wimbledon) that run the STAR diagnostic tool for a cheaper price than MB?
Thanks,
Baz.
