You might be surprised; good minis fetch good money, especially the old ones. Now there does appear to be a few issues here (wheels outside the body is quite common - might be cooper wheels) but assuming its striaght then I could see it selling. Main issue, as always, is originality. The number you see of original minis for sale that have been reshelled and the engine changed is amazing!
A 998 cooper in good nick is over 20k and a 1275s 30+k. Its mad. I'd love another as my very first car was a 998 cooper bought for £1500 in 1988. It would be more like £15k now.
