I thought it was @Mark G 's car at first after reading the notes about the satnav......
"The sat nav system is not usable here in the UK. I have no reason to think that the system does not actually work (in Japan) - however, when in the UK, the system seems to think that the car is out in the ocean somewhere"...
Interesting car but can't see Joe bloggs paying 15k, agree 8-10k is more realistic. Good luck to the seller, good write up to be fair.
