Not got a Z yet but currently looking to buy a 370 with a few tasteful mods.
Not in a rush so will see what comes up.
Budget would be up to about £12,000 so would think that I would most likely be looking at a 2010/11 car.
I have already got a Nissan with a 3.5 V6 engine but it is a complete opposite to the Z being a Nissan Elgrand MPV which I am currently in the process of converting to a camper and even though I said I would't when I bought it have got caught up with the modification and upgrade bug, big wheels, uprated exhaust and handling etc.
I have had it just over a year and self imported it from Japan.
