I am retired. I drive a 2000 Jaguar. In a couple of years I want to get a new jaguar.Would I be more prudent to lease a new Jaguar or buy one? I drive about 12,000miles a year. Thank you very much.

Depends on your needs and finances. Leasing is a good deal for people who frequently turn over cars. Generally a purchase is better for people who hold their cars for 6 or more years.

Here's a good article to help you decide: http://www.leaseguide.com/lease03.htm

I will add it is always better to buy a one year old car than a new one, with most you still have remainder of warranty and you don't lose such a large amount when you drive over the curb of the car lot.

Buying a one year old car, and keeping for two will save you a lot more money over the long run. ( personal opinon)
