I like how you sum’d it up...
The devil is in the details. BEFORE purchasing the extended warranty read the very fine print and pay particular attention to the exceptions. You may find that there are multiple exceptions resulting in non-covered items.
Factory vs Service Contract (S/C) is difficult lately though. I’ve seen some posting GMPP is leaving them high & dry on diagnostics and unusual occurrences.
A bit to chew on though, CA has the most stringent standards for S/C being sold. Just a few sell them on vehicles North of 90K. Ally (yea, the bank) and AUL are two that exist here in Cali. Both are monitored by the CA Dept of Corporations and CA Attorney General.
I was quoted $5.9K by Ally for a S/C on our 09 Platinum w/ 130K mi. The Rep from Ally told me that their S/C sold by them in other states are mostly governed on what CA demands of them. Once a S/C is established on a vehicle sold in CA they slice off what’s NOT required by the other states they sell the contract in.
Unknowingly, I’ve promoted S/C but should of been promoting S/C sold in Cali. The only reason we have our 09 Escalade Plat today is because the S/C purchased on our 08 Denali AWD in ‘14 @ 96K paid almost $15k in covered items like p/s rack, pan & rear mail seal (2x), Alt (2x), radiator (2x), rear air shocks & comp’r, seals at rear brake /axle plates and all other seals fluid associated & water pump. There’s a few more but can’t remember.
So much documented, deferred and current maint was preformed by the S/C on a one owner truck from ‘14 to ‘20 in 40k miles the truck sold for $7K less than what we paid for it ($19.9K). The cost of fixing the failing black paint and cracked dash are the factors the prompted us to sell it last Feb. The proceeds from that sale paid for all but $2.5K to purchase our 09 Esky Plat that has super thick white pearl paint and a leather dash that won’t crack.
No S/C was purchased on the 09. The 08 trained us on how to care & maint the Esky. Figure we saved $68k on depreciation w/ the Esky purchase and it’s all due to the Yukon’s S/C allowing us to sell it private party. Resale on on the 07-09 NNBS are crazy high. I figure resale on the 12-14 NNBS will be identical. So yes, if you get a good warranty or S/C you can bank on your NNBS purchase. Purchasing Esky to obtain the proven tri coat paint and / or leather dash will let you be immune from the two most expensive and annoying failures on this series of trucks.
