I have just bought a W212 E350 CDI saloon for my wife from the main dealer in Edinburgh. Now, normally I check everything like a hawk but this time I didn't. All the tyres on the car said Continental and have plenty of tread depth but, on closer inspection when we got the car home, one of them has a Porsche N2 93Y load index. So I contacted the dealer who is very well known to us and their reply is that the 212 350 cdi is fine with anything from 93y to 97y on it and they will not be changing it. I called the insurance company and they said “If it passed its MOT, then we have no issue with this “ Your thoughts on this please.
