People put too much value on extended warranty... if the car is 5-6k cheaper, I would just buy the car without extended warranty, sell it in 2 years when the original warranty runs out, and then buy another pre-owned with still 2 years of remaining warranty. Or if you plan to keep the car longer term, just drive it without warranty... I doubt 2 years of warranty is worth 5-6k dollars...
There's no way the selling price of the car would be 5-6k different due to warranty. I doubt you get even 20% of the value of a warranty at trade-in.
I fully feel this way about ICE cars. There's just something about the high priced door handles, pano roof, and massive display that has me uneasy without an extended warranty as an option. Not saying that I will buy the warranty right away, but the option to do so is nice.
