Can't see where it would be advantageous to not have some form of warranty coverage on newer vehicles, there's just too much tech in them that the vehicle depends on to run.

Lose any part of the system and it just might not run, and parts for new cars are not inexpensive.

It's more likely you'd have a $3000 problem with a new car. It's not like having a 70's C10 pickup where you can work on it with a socket set, screwdrivers and buy the parts at autozone.

I bought a ford (fix or repair daily) extended warranty from the dealer.

It paid for itself a couple of times over.

I would only buy a manufacturer's warranty.

It was a wash when I bought one for my Subaru.

Was a waste of money on my Honda. I should have bought the tire insurance for the tires.

Never, ever, not ever buy a 3rd party warranty. Factory only.

The 3rd party places look for excuses to deny coverage. Some of them require you to pay for pricey maintenance at the dealership that you're buying the truck from and if you don't, they will say you didn't follow the terms of the contract and breached it.

Don't ever buy a 3rd party warranty. Factory only.

I would advise against it. I purchased my truck back around 2014, it was a 2005 with 40k miles only. Only thing it had on my test drive was a clunk in the rear end. The dealer talked me into getting the extended warranty, and luckily, it was a cash reimbursement of about 3k if it passed 4 years, and didn’t go over 107k miles on the truck. The issue was, it was only for major repairs, once I read into it in better detail, and I had to jump through hoops t cash it in. I was at 102k miles, and at the end of the warranty, I had to take a picture of the odometer, which is understandable, but then I had t9 also get a notarized statement of the pic and explanation for the cash request. Luckily, one of the people I worked with was a notary and she happily did this for me. It took a few months though to finally get my money back, and of course the company had changed slightly, and even though I had a signed contract, they changed the rules a bit. I did get my money back, thankfully but I will not do that again unless it’s a factory warranty. Oh, and that clunk? It was a loose rear bolt on the stabilizing arm in the rear axle if I recall, not sure if the description is accurate, but basically, a loose bolt. Nothing wrong with it at all once we tightened that and made sure all was good.
Edited to add: I’m still driving it, it did have some maintenance and repair issues, but later, after the warranty would have expired anyway. Mostly basic stuff.
