my math is
if you get a 2014 for 9 % off that is 119,210 on a 131 k car. a yr earlier model should be a 10-15 % cheaper than that number which is 101,328 assuming 15 % additional discount. as when you trade in a car, the trade in is affected by the model year of the car irrespective of the time you actually purchased the car. so that is closer to 28 k discount on a 2013

 

Buying "year end" is only a deal if you routinely keep it many yrs ( like 5-10 ) . If you flip often ( every 2-3 yrs ) , better to pay a bit more for a just off the boat incoming model year to get the most "use it and sell it " value because the model yr delta in wholesale / trade in first few yrs will eat up any factory incentive "trunk money" the retail dealer passes on to you to clear out the outgoing model yr .
