I'm considering selling my Protege 5 and buying a friend's WRX. My car was recently in a low speed accident that damaged the front and rear bumpers (got rear ended at a light and pushed into another car). All the damage was repaired (bumpers replaced, no frame damage). The car looks in perfect condition.

As far as I can figure my car should be worth between 11,000 to 12,500 if it hadn't been in the accident. (It is a Red 5spd with 23K miles, leather seats, power moon roof, plus the standard equipment and I live in San Jose, CA.)

I'm assuming that the repair work would show up on a title search so how much of a drop in resale price should I expect for fully repaired minor damage?
