Mercedes Benz Inverness Arnold Clark Put our CLS250 in for oil service, While in the car engine was basically destroyed as a result of what can only be described as negligence.. I refused to take back an 18000 mile car with an extensively repaited engine. After parting with £3000 we accepted (unseen and untried) ML as a replacement. We hated it. Noisy and nothing like our top of the range CLS that they wrecked the engine in.We asked for it to be taken back after two days and lost £3000 after 2 days.. After much discussion we opted for a 350GLE at an additional cost of £9000. The total cost after putting our car in for an oil service is £12000 through no fault of our own. Since day 1 this car has had a sever vibration problem. It has been back four times and after 9 weeks we are told by Arnold Clark Mercedes Inverness and Mercedes Benz UK that is normal and is part of the "chsaracteristic of this model. Mercedes say it is caused by the "resonance" of the 20 inch wheels, the tyres and the lowered suspension. That was what the car came with. SO DONT BY A 350 GLE as both Mercedes UK and Arnold Clark say that is perfectly normal. I am attempting to get a resolution. I will post here all the updates.
