I was at least one of the voices warning against a Nissan with a CVT.
I’d also agree with NOT getting an extended warranty. All you know for sure when you buy one is that you spent the money; it may or may not cover any repairs.
If you actually have the cash to buy an extended warranty, you’re far better off keeping that cash in the bank in case you ever need it. If you have to finance the warranty (“roll it into your payment”), just don’t.
