Love Kas, glad there are some other people out there who share the same enthusiasm!
We owned a silimar one in black which we were really sorry to see go, it was a luxury job with tons of extras and in really good nick, sold it privately to a local young lad but I suspect he wrote it off as I never saw it again and it isn't on any dvla records now, thats life I suppose!
Wife has had a couple of nice better spec cars since the Ka and she still misses it a lot!
I think these will be sought after in a good few years, and if i had the space I'd buy one to keep as they're so cheap now it's not like youre going to lose money on it. Good luck with the project!
