Hi John, welcome to the forum. Hope you find enough information to assist you in your quest. The problem is that there are many thousands of faultless Jaguars out there that we, on the forum, do not know about so it will be wrong to assume a mark to be bad due to the small amount of problems that we do know about. All manufacturers suffer with good and bad marks so it is down to the customer to decide. Good hunting.
