Look up prices of a $80,000 Mercedes that is 15-20 years old, basically giving them away, same with any "luxury" car, and most "sports" cars. The problem is, cars are too good now. A 15 year old car is not worth much because over %50 of them are still excellent drivers, and there is %10 the demand for them. all the 7-10 year old cars are excellent condition, and are not much more money.
