Is it more adavantageous to do the following. I am now using my shooting car for appox. 30 k miles a year. The question is if I buy a 1 year old left over & trade it every year, it is now a 2 year old car with 30 k on it or if I buy a curent model & trade it every year with the same mileage ? Am I taking a bigger hit for two year old with average 15k/yr or a one year old with "high" mileage 30K?
