Stay with me while I try to explain. If you average 15K per year on a car would you:

A) buy a newer, low mileage (lower end) car or

B) buy an older (higher end car) with more miles

Example: would you buy a 2012 Chevy whatever with 25,000 or would you buy a 2008 Lexus with 70,000 (priced exactly the same).

The above is just an example.
