Dont think you will have much choice, cheap, no MOT and full of rust, thats most minis isnt it!! Sorry, but had my fair share of them, used to rally them!! Got some spares if you ever need them, give me a shout!
There is a Mini restoration garage in Tranmere just opposite the sportsmans pub, he has a mini that he is selling for £1,500 that looks as sweet as a nut.
