Welcome to the forum!
And thanks for that, Lladnar - ex is a has-been and a spurt is a drip under pressure, I know the drill.
I think the Thai build is probably not quite as good as the Japan build - ask Dave, his truck is just great and has gone for over 200,000km whereas Aido is still looking for a backhoe. That said, I'm no expert on the two together - I just read opinions here, and get the feeling that while the Thai trucks aren't quite as good, they're not really bad either.
I do agree that white is the better colour, although silver doesn't show the scratches as much it is a harder colour to match properly.
Personally I prefer the Spanish build, but that'd set you back a fair bit more coin too.
