One of the main importers does the UK registration and will put a pop lid on or waxoyl treat it for not much. Iirc£350 flat rate to import and get it to UK spec and registered. Then a lid is a grand or so I when I looked and waxoyl something like £150 from memory. So a £5995 2008 or 2010 Alphard.
Some are already treated before they leave Japan. I think parts of Japan can be wet and icy with salt too. However I've only seen some descriptions say its treated underneath. That site does not actually tell you much about the vans except a load of acronyms like PS for power steering, age, mileage, location, fuel, gearbox, engine size and sometimes the engine in it (makers letter codes). Nothing about condition unless you can read the car check report for the auction (in Japanese only).
Age is usually 2000 to 2014 and anything from £4000 - £12000 on one site I've looked at.
I knew the mazda bongo and ford fred are the same but I recently read that Mitsubishi delica was made by mazda too until Mitsubishi started to develop its own. Nissan too was the bongo with a different shell I think. Then after mazda found out the nv200 or nv 220 was being developed in house at Nissan they separated. Daihatsu also had links with mazda. Of course ford owned mazda at one point but sold up after GFC happened. Not before they took the interesting mazda ideas and one of their main designers. I heard the grand c-max took a lot from the mazda 5 such as the middle second row seat that folds into the side seat. A neat design. So I guess a lot of these mpv vans are very similar for good reason. Of course I have no idea if they are all mazda made or that's not true that I read online.
Most of the ones I've looked at tend to be 30000 to 100000 miles for vans typically 2005 to 2008 even 2000 vintage. Overall low miles I think. IMHO anything under 10k per year in cars I'm usually happy with.
This would be our only motorised transport (buses and trains excluded). It needs to fit in height restricted carparks and carpark spaces. Comfortable drive but I'm not fussed by sporty performance. I doubt fuel economy is possible with a 3.5 litre petrol engine and 4wd. I think they do come with 3.5 litre diesel at times but japanese drivers seem to prefer petrol. Family is two adults and a 6 year old. Bikes are hopefully able to be stashed inside with camping gear. It's north Lancashire near the coast so snow and truly bad weather isn't common. It has caused us problems once with our seat car but the previous Astra coped with a lot worse including several cms deep layer of snow using summer tyres. I'd like to say it was driver skill but I believe it was more about the car. Maybe the skinny tyres. They were pirelli p3000 on the drive wheels but a lower spec on the back wheels. All driving on tarmac ranging from potholed local roads to motorways (which can be badly potholed in places too).
I guess we would like more internal space and a place to sit out after walks, possibly fit some kind of camping stove and table to make it a kind of day van.
Would anyone recommend one of those options over the others? Or is there a UK supplied equivalent worth looking at. It seems to me UK spec vehicles that size aren't as well specced out but smaller and more efficient engines.
