Welcome to the forum!
There's bucket loads of zeds for sale these days so you have plenty of choices. I woulodn;lt worry too much about imports as many many people here own them, myself included, and as long as your careful when buying you will be fine - much the same as buying any car!
If you find any on Autotrader or pistonheads etc post a link up and people can tell you if its a good deal or a lemon
