Evening, Need your help & advise... Ive got a 2002 merc cl55 amg and its now been in my local merc agent for around 6 months, it went in for its ABC Suspension not functioning properly..problems including sinking to the floor, sitting unlevel & jumping in the air when the car is switched off!

Anyway so far i have payed out £3600.00 Yes £3600 and i collected the car after they had supposedly fixed it in first 2 months I got 3 miles up the road when the car uncontrollably started moving up & down and side to side....Drove it back and they said they would " Oh ok we will look further into it & contact germany for assistance" well 4 months later they have said they are still in talk with germany and After a visit last friday they Say "We dont currently know how to fix the car"!! hello your the Mainagent & AMG Specilist...Clearley not that Specilist!

So i have no Cl-55, Currently down £3600 and have no courtesy car not even an offer and a Cl-55 that has depricated £1500 since its been in there,

They promise to call and keep me updated! the calls never come..end up going in there, getting ignored or moved to a different section of the dealership so other people carnt hear they carnt fix the car!!!

Where do i stand now???? Any Ideas

Thanks Guys
