Forget this saying of "It's how you maintain the car that matters." Let's say this vehicle is religiously maintained wherein all maintenance schedule is followed religiously without any lapses. The materials used for maintenance such as engine oil, brake fluid, etc. are genuine premium original products. Price isn't an issue as well, it doesn't matter if one is a lot more expensive than the other. The only priority is the overall quality of the vehicle.

Which should one choose? Japanese, American, European, Korean, or Chinese?
