I was going to say it's damn rare for a UK car to have frost coloured leather seats, then realised it's an import and doesn't have heated seats. This also means the sat-nav is probably in Japanese and useless unless it was imported from the states and also explains why it has a pull down cover on (the UK cars didn't have a cover on the 313s I believe - mine doesn't on the roadster anyway). I also can't see the Brembos in the photo, did JDM spec cars have these?
Could be worth watching though but as above I doubt he'll sell it for a stupid price and will pull the auction, if it reaches a reasonable amount I'd definitely be going for a UK car with the current market prices.
