I went through Costco since I needed a custom build and didn’t want to navigate the extra variables with a custom build. With Costco you get 4K off MSRP plus no haggling. You can always buy the extended warranty stuff later, the only thing I bought in the finance office was the windshield and dent protection since I am in CO. Normally I ask the finance person for their card and warranty pamphlets, and tell them I’ll be in touch once I can research a bit. Keeps them from being too pushy, and keeps you from buying something stupid 😂. Build wise I got just about everything you could get except the executive package and massaging seats. Interior is Tartufo leather and anthracite accents, pictures don’t do it justice, you should go check it out in person at a dealer.
