Good luck with your search. I'm in the hunt for a Zed too and all the advice I've had so far is to be fussy and get exactly what you want in terms of spec, milelage, colour etc etc. No point comprimising, it will only tarnish your ownership in the long run
I've only been seriously looking for about a week and ive found so many cars that very nearly almost fit what i'm looking for, so I'm confident that in a few weeks the perfect one will pop up at the right price fingers crossed anyhow hehe
