Have a European car and a Japanese one, one is 6 yrs old, one is 8. The Japanese one has only got regular service so far with no additional work done, besides a battery change at year 4. The European one, I have changed small obscure electronic parts to rebuilding the engine head from a donor engine, that essentially cost 1/5 of the insurance value of the car. The European one rides well, is nicely tuned, but I am going all jap in my next change lol.

European car parts are also about 3 times the cost of the Korean ones, and at least double of the Japanese ones, so servicing the car in the company workshop costs about 3 times as much as servicing an Asian car (in my country). If your country has a good service network for Japanese cars, like a Toyota, Honda or Suzuki, consider them, the total cost of ownership can be much lower in my opinion. If your country doesn't have that advantage, then the point is moot.
