Well it doesn’t meet the Japanese requirement, but South Korea is quite close.

I highly recommend the Kia Picanto, with a 7 year warranty you can’t go wrong. Mine gets 280 miles out of a £44 tank, and a dealer service is arround £250 each year.

I’m not sure if they are still doing their scrappage scheme, but you could buy an old car for £10 from eBay and use it to get £2,000 off of one of their cars in the dealership too.
