Subaru Impreza WRX
How little you'll save buying used:
This sporty version of Subaru's popular Impreza sedan costs roughly the same whether you buy it new or used, thanks to strong demand and limited supplies.
Lyman says consumers in cold-weather states love Subaru's all-wheel-drive systems -- "a high loyalty that increases demand and reduces supply in the used-car market because people tend to hang on to them."
Add in the fact Subaru hasn't redesigned the Impreza WRX in five years and you'll save little buying one used instead of new.
TrueCar found that the average new Impreza WRX sells for $30,057, while a 2010 or '11 version costs $26,786. That's a mere 10.9% difference.
