Overhaulin' - how much does the cost of a new car drop after the next years model is redesigned?

how much does the cost of a new car drop after the next years model is redesigned?

for example how much would a new 2009 subaru cost after the redesigned 2010 models come out?

on the lot your only difference is what ever incentive the mfg is giving but in the market place if you were trading you can expect an additional loss of about 15% on top of normal depreciation.
It depends what subaru it is...eg impreza, liberty etc. And also if subaru are planning on making a new MK for that certain model. All new cars drop in value so I would estimate if you buy the car new it will drop in value by 25% (ish) within a year :)
A car's redesign has little to do with a previous gen's depreciation. Expect almost any new car to depreciate 20% the second it's off the lot. From there, there is a wide range, according to make/model, of what depreciation rate will continue from there.
