Thank you all for the responses. I think while I'm ok with this kinda thing, after proper checking it out, I get the feeling that resale is where the main issue is going to be and as I am yet to own a 350Z I can't say for sure how long the love affair will last.
So the search for a UK model 04-05 for under £6000 with as low a mileage as possible and NOT cat C or D (or even A/B Ekona :-) begins!
Again thanks for the help, and of cause anyone that is thinking of selling such a car would be welcome to PM me ;-)
