Very sound advice thanks fella! I have read about the steering lock issue and I will check the vin and make sure the work is done if not, I'm not actually buying from a dealer but privately from someone that's not long had it from a dealer so there is still 8 months warranty on it. Any niggles I find I will make sure Nissan sort it.
Apart from the servicing then to make sure it's had them on time, I did see the yanks where having oil changes every 3K miles but I assume that does not apply to us in the UK and that it should be fine on the standard P service schedules?
The guy assures me the car is mint and that I won't find a thing wrong with it, alloys all unmarked (I'll be having them done high gloss black anyway)
