Hello! I have a Nissan Cube which is so quirky, I absolutely love him and he's great - no probs at all on long motorway hauls, good fuel efficiency and it's basically like a little TARDIS space-wise. He was brand new to the UK when I fell in love with him and I've had no trouble at all with insurance or getting work done - just use normal providers.
The only issue has been the built in sat nav/entertainment system, which obviously speaks Japanese. There's a shouty voice which briefly says something when I start the engine - which I don't even notice now - but for ages she would randomly yell stuff at unexpected moments and start showing me maps of Japanese places, which could take me by surprise and be bit unnerving.
Google translate on my phone - pointed at the manual and at the sat nav screen - helped me to turn off all map notifications etc, so she doesn't do the random yelling any more. Unfortunately, while I was messing about with things I must have pressed reset something thing because the car wouldn't start and I had to get the recovery guy out who did something to reset the ignition system and no probs since - he seemed to find it amusing when I waved the huge instruction book at him, all in Japanese, obviously.
The sat nav/music system can't be reprogrammed for the European market, so would have to be totally taken out and replaced - and to get one with really good maps is quite costly. So now I just use it for playing music and use a Garmin sat-nav, which is really good.
I couldn't be happier with my Japanese import, really!
