I think it started life as a 2ltr petrol with a 4spd box, as theres still a choke lever, and the gearbox pattern displayed on the dash. It now has a 2.5Di with a 5spd box.
I've attached a photo of it, on the long shot that somebody will know what i've got!!

Has anyone else had this problem before, or is it just me being stupid?!
