My only complain about it is that the engineers who designed it are sadistic, it's a pain to change the oil filter or the battery

They're not sadistic, they just threw the dealerships a bone so that more people would come in.

A good argument against it would be that rather then buy 2 cars in 6 years you get one new car and have it for 6 years. I'm honestly not sure, but so far I've not had reasons to regret.

That's basically what I have. A good new car for ten years.
