hi there
i bought my first impreza off them just over 2 years ago and after i bought it soon realized it had been in an accident but well covered up and it had not been registered. also i paid well over the odds for it. Also the 1 3 or 6 months warranty you get isn't worth the paper its written on they'll try avoid any repair like they did with me. i take it its Dee Ireland who's selling the car? i'd ask everything you could about its history, i'd hpi check it and go over it with a magnet. hope this is some help
