To answer my own question...
After poping into my local dealership at lunchtime, there are no deals at present.. I managed to get £1.5k off the list price (Night blue non gt with Nismo kit, which would have to be ordered) but thats about it, they could come nowhere near the price listed on the drivethedeal website... infact the salesman claimed never to hear of it and suggested that the cars they must be selling are imports....
Anyway i asked about a part exchange (05 White 350Z ST) and the guy who does the evaluations wouldn't even give me a price because it was an import, he claimed that all the parts on the car are different to a UK one and so it would be impossible to fix should anything go wrong.... Clearly this guy was clueless as they are all made in the same factory..
Also.. i was told as it was a non GT the list price of £2k extra for the Nismo kit did not include the cost of fitting.... Apparently the price quoted is for GT models only... what a load of bull
I just laughed and left..
