Wow. I just picked up an almost identical spec about 6 weeks ago for $520K. Mine had 12k miles but still….. Market has gone absolutely bonkers. My dealer told me he moved on for a little over 700 recently.
Most high end cars in Japan including luxobarges are LHD as it's a status symbol to have LHD in their country. There are some, but very few RHD exotic cars. I've noticed the big price difference in Japan and EU vs USA. My best guess is a lot more US buyers are more into the investment/speculating aspect on how much it will make them in the future. Whereas in Japan and EU I see cars with more miles and even some modifications you won't see here (especially Lamborghini in Japan). It's starting to make sense for those of us with either multiple residences overseas or frequent visitors of those places to buy and keep there and use there rather than have one here. That's not even going into things like better road quality and lower risks of theft and car accidents of having an exotic in Japan vs US for example.
