Cars and other luxuries are heavily taxed. A typical automobile costs $100k. Not a high end car but a cheapie beater. Gasoline is heavily taxed and expensive.
I have not lived there, but am quite familiar with their tax structure. Yes, they do have some high taxes as you mention, but his concern is with the income tax - they top out at 20%, vs our 37.5 - and capital gains tax, of which they have none.
I doubt he cares how much a car costs there.
