My daughter and her family have been living in Tokyo for over 2 years where they have a Discovery 3 bought when they arrived. It has proved an ideal car for carrying around their 3 children and all their paraphernalia and sports equipment, with occasional use being made of the extra seats. They are due to return to the UK next year and, as second-hand values of 4 by 4s are even lower in Japan than here and shipping costs are currently low, are considering shipping the car back. The problem is that, although of course they are RHD, the Japanese models have a 4-litre V6 petrol engine not sold in the UK instead of the usual diesel. Is this likely to cause major problems with spares, servicing, etc.? Other than having to pay VAT on importing the car are there any other expenses or problems which they should consider?
