I guess it depends what you buy. My car stores all kinds of info in the key fob, including maintenance records, average millage and even driving style. It's also very easy to tell when a car is been abused or babied. The warranty also covers everything bumper to bumper, even the shinyness of the paint
And that new car feeling fades fast, especially after you bought a 2011 civic si and find out your friend just got a loaded 2007 335i BMW for close to the same price. Or when you get hail damage or when your wife drives it into the garage
Money is only money but value is whole new ball game and I'll take the feeling I got the most for my money over a new car feeling any day.
