Trojan Cars, in Southsea, Hampshire, have a Vauxhall Vectra 1.8 petrol, with MOT, for £495, listed on Pistonheads
Don't know any more but I had one of those in the late '90's and it wasn't a bad car - dead reliable over 132,000 miles.
They also have a Rover 211 listed on their stock list - described as "beaten and bruised" but only £295 and has MOT until April.
