I just bought a new '22 yukon xl sle for about $4400 under MSRP. I feel like I did pretty good especially considering how aggressive they were with my trade. Im wondering if there are any good extended warranty options out there. With my ford I was able to buy directly from ford and it seemed like a pretty good value, and was seemless when I needed work done. Does GM offer anything similar, or am I on my own to find a third party?
