Hi Trevor, You have about 18 months to go. My Jaguar Warranty handbook does not mention the compulsory maintenance by a Jaguar Main dealer, but stipulates a VAT registered garage and use Jaguar parts. The Sale of Goods act of 1979 comes into play if the car is faulty in any way, but that would have come to light by now, anyway. I have wandered around contract law and the majority conclusion is that if you have your car maintained by a VAT registered garage and the maintenance schedule is followed using genuine Jaguar parts/recommended oils etc, then the warranty remains valid. This will have to be shown in the service book. I would reply to your dealer and tell them that they are wrong. And if your wife thinks you are turning into a grumpy old man, she should have words with my wife about what grumpy old men are like. Regards, Peter.
