I don't think I've ever driven a Japanese car come to think of it unless one I borrowed from a friend in college or one got as a loaner car from an autoshop was one.
All my previous cars were American, I have a Hyundai now.
I don't recall ever renting one, I think I've only rented American and Kia (so also Korean.)
However that current Hyundai has a flashing check engine light. I don't really need a car now so I'm not in a hurry to get it fixed but until I do I'll probably drive my mom's if I have to...a Subaru, so Japanese.
A flashing engine light is usually a sign that the car is misfiring, which is worse than if it’s just a non-flashing engine light. The latter is usually some smog control that you can easily ignore.
