Is it a P55 by any chance?It's a Scott Sportster, mid range, price in the shop was £420 if I remember correctly, but it had already been reduced being the previous year's model.
I like the Scott Sportster, I have a well looked after P4. I think they only manufacured them for a year. No disc brakes but can be fitted, a nice bike.
Plus I have a couple of MTBs that I have repaired and built up from spares, to do a bit of rough stuff when I have urge/time.
