Looks as if they hold their value pretty well. Then again getting a great deal on a new one helps tons too. Your question is 2 fold...great for sellers not so great for buyers. Case in point, mine is an '06 bought on 8/29. MSRP was $30,515 and I paid $27,270 dealing with the internet salesman. Looks decent in the pic and I see it has the quarter window scoops. Any other mods? I know there are threads on here about the crazy used prices already. IMO that is not a bad price(not sure about the mileage affecting that price, good or bad) to get one of these great cars. It is leaps and bounds over the '00 GT I had for 4+ years!
Have you owned any Stangs before?
I say if you can afford it...GO FOR IT!!!!!!!
