While Truecar gives you the closest match, the prices vary according to the market trend. Check the respective car board. When I was out to buy a Forester/Outback, I checked their forums and both of them had a thread 'Prices paid'. I made an excel sheet with all reported prices, with trims, regions etc. and came to my best guestimate as my asking price and the range I want to compromise for.
Later on, a local Subaru enthusiast informed me abt a specific dealership and specific salesman to get the best price. I seriously hate haggling so that was a blessing. Next month, I am clocking 3rd year on my Forester without having seen the face of the salesman or the dealership that sold me it. So also check if there is any dealership that gives you the 'best' price.
