Good point on the radio, sat nav, insurance and grey history aspect! Think it was imported with 20k miles on it, so that is half of it's mileage spent in a foreign land!
In reality the main pull i've had to this JDM is that it already has front & rear bumper mods, as well as skirts, exhaust and some nice alloys, so it would cut the amount of work i'd need to get done on it to the spoiler and the interior + gadgets.
I have been toying with the idea of spending £6.5-7k on a standard UK GT model, since there seems to be a lack of already kitted 350z's out there with reasonable mileage.... and then getting all this work done myself, but from what i can tell getting a aftermarket kit will set me back around £500-700, with about £800-1500 to fit it depending on the difficulty and paintwork needed, so that approach does seem to be more costly at the moment. May just be a case of waiting for a bit to see if a pre-made UK GT comes up!
