Condition will drive price, and I think if the body is good straight and rust free, with full service history, you'll get your money back by not having to lash out on repairs.
May depend what you want to do with the car. Run the standard car or "pimp my ride" (meant of course in a good way..........)
The forum has seen some nasty rust on these (is it the rear window area?) where a repair and good spray job could cost a great deal. Having said that the colour is not my favourite and when I see SEC I see jay's car, or KLP etc - which take quite some investment of time and effort ................
The prices are just guides and Barons very frequently sell cars under guide.
