Hi, Can anyone help please. My 2001 CL500 failed MOT yesterday - no fluid in rear offside shock absorber apparently. Mechanic says expect Merc to charge £1500 to fix it! Does anyone know where I might buy one without going through the dealer (I suspect they may be cheaper elsewhere), and give me an indication of how easy these are to fit - looks pretty straightforward - but I believe they need balancing up and this can only be done by the main agent? Any idea what they may charge for this service? Thanks.
