I will extend that warning to any BMW, Porsche, Audi, Fiat...... You get the picture. I have repaired cars that were clearly a problem before the warranty had run out and the local dealers told the owner there was nothing they could do. Outright lies and half truths were normal and in my experience were just part and parcel of the way things work. I had a wonderful relationship with the old guard at the local dealers , [Viti Bro's and Benz of Warwick RI], but when a couple of the old timers left they were replaced with what can only be described as money sharks.
