Right. Consider it Used Vehicle Buying Lesson #1 then: "used" isn't specific to older vehicles.
It ignores 1 important fact: they are still closer to the next service than the a new car. A car 1 year old can still has wear and tear. Typically not big, but use none the less that varies from owner to owner. There's no guarantee your 1 year old car sits in condition that of a new one.
You listed them as the only ones you've heard of that would have capped rates & fall under low-tier. They just so happen to be the marques who sell cars in this range as well.
Of course it applies to new vehicles as well. So logically, if it's not going to be any more or a negligible difference....paying less money for a used vehicle in the first place means you're still saving money over the same time period.
The difference here is most people don't take new cars to an independent because warranty work covers them. And again, on cars these cheap, warranty work is going to cover near everything that will ever go wrong for a long period of time.
Well the Honda in question is actually an Acura in the US of A but from other users' experience yes, Honda Australia charges through the nose, actually rivalling the likes of Audi/Volkswagen for servicing charges, and so does Subaru.
Then it sounds like a regional issue. Then again, I have yet to hear of anything cheap when it comes to buying cars in Australia. Your tax is insane.
Buying a used vehicle that still has a warranty and has taken a hit in depreciation is "smarter", as
@Crispy said. You can opt for a higher trim level, you still have the peace of mind.
But of course, everyone's experience is different.
It again ignores use and age. A 2-3 year old car with 20-30,000 miles is also 2-3 years/20-30,000 miles closer to an expired warranty & no guarantee the previous owner treated it right. They become no different from a CPO that is factory - certified, though these are arguably the safest deals. Problem is not everyone honors them and not everyone agrees on the terms when you buy a used car still within warranty.
Both have their pros and cons and require a smart approach, but from my experience with both, buying used has always been more of a hassle mentally and financially because I have to spend the time searching through numerous more dealers that range from manufacturer to shady con men & have PPIs done to ensure I don't buy a money pit. Buying new has always been straight forward because I know what I'm paying up front with no surprises.
That's why I say it's a more financially sound decision to go new. Just like letting your money build interest in a bank compared to laying it out on a poker table.
