I have 40 and 21 year old Jaguar engines that don't have the reliability problems of 6 year old Jaguar engines. It just sounds like Ford "quality" (or the lack of it) to me. Maybe I'm wrong, but there's nothing like a 3.8 and a 4.2 Jaguar engine. I'm not saying the old Jaguar engines are perfect, but they are more reliable engines no doubt, they are time-tested. But of course, I am talking about well-cared cars and their engines. You can buy a Jaguar, or you can buy a choice Jaguar. The last option takes time and a lot of research. I spent 10 years looking for a choice 1960's S type, traveling and checking dozens of S types before I found my car in San Francisco, a perfectly preserved example. Yes, the car brought me home 2,900 miles from San Francisco with only a flat tire and NO knockoff hammer in the trunk. It had everything but the hammer! Thanks to a Texas rancher, who had a sledge hammer in the back of his truck, I was on my way in 30 minutes.
