Why would you even bother with a nice car like that in Thailand? Don't they still have bikes with tents on them?
It's like driving an Aston Martin in Rwanda.
I was driving SUVs here for 16 years here - mostly because of the kids, wakeboards, bikes etc - this time I just decided I wanted something a bit more fun to drive. They have some decent roads here, although Bangkok does get gridlocked.
The biggest upsides - you don't get pulled over by the cops in it and when you drive into a full car park, the security guards will guide you to a "pride of place" area where you can leave your car. Not sure why - but I suspect they like to have nice cars lined up at the front. So basically - you'll be driving behind 4 Toyotas all looking for spaces, then you hear a whistle, the guard waves you over, moves some traffic cones and gives you that place to leave the car. Bung him 20 Baht (75c) and you'll be waved in every time you go there.
Poor countries like Thailand aren't void of money - it's just not very evenly distributed. Go to Starbucks @ Tops on Thong Lor any Sunday morning and you will see about 10 $1million+ cars there - all owned by guys that look like they should still be in diapers. A lot of them are illegally imported because of huge car taxes (even my 320i cost $80k), so these guys are probably the sons of politicians, senior police, senior armed forces etc. - lots of money and total exemption from the law.
Bottom line - even a cheaper BMW like mine is fun to drive. I rented a new Honda Accord whilst waiting for the BMW and it was like steering a fish. Nice, smooth ride but no guts and no personality.
