You may be preaching to the wrong congregation, I bought a new car shortly after I graduated from college, since then for my daily drivers I have bought low mileage, well cared for cars and driven them for years.
Sure its an appealing car, but even if I were inclined to buy a new car, it would not be a high end luxury or sports car, I just don't have the kind of money you throw away on those cars, 10 year old Audis, BMWs, and Mercedes sell for the same money as a used Honda of similar years and miles, generally speaking Jags are even worse, expensive going in and big hit going out.
Even if resale was not an issue, if I were to spend that kind of money on a car I would get a classic Jag or similar, not a new one, cause that is the kind of car I really like, to me the picture above says it all, no comparison at all between the old car and the new in appeal to my eyes anyway.
