The 9k one will need an instant 500 in parts, more in labor if you don't do the timing belt/wp and regulator yourself. Also, the extended warranty for the cam follower is expired (100k miles). The price is low and he seems to be motivated, this would be appealing at 8k though. I would pay more for a better car, but the price is good.
The third one looks like they used armor all on all the interior surfaces, seats included. It also has the s line front end, wheels and door blades, which are not factory on 05.5 cars. Id skip it for the price honestly.
The second one seems to be the best of the 3 imo. still has some cam warranty left, looks stock and in really good shape. It has xenons, bose, premium package (rain sensing wipers, auto dim rear view morrors, power folding mirrors, etc) ps quartz gray is a sweet color, offer 11k and enjoy! Pps, make sure you do timing belt and cam follower if they haven't been done though.
