It adds up pretty quick lol. Sticker of $80k is about normal for a KR, and maybe $85k for a Limited. Add $20k for add-ons like GPS tracker/theft, FordPlus super-warranty, various fees, taxes (prob $8K on this one), and yes (everyone hates this one) a "Market Incentive" anywhere from +$1k to +$20k depending on how rare or hard to find the vehicle is. With a Chinese chip shortage that has parked 100,000+ cars from about every manufacturer on the planet, finding one is problem #1 then finding one without dealer mark-up hanky panky is even tougher. So in reality an $80k sticker KR can add up to $100k pretty quick. It's why I bought a new 2020 KR with ~500 miles on it, because they were ready to deal. [Fingers crossed] here's hoping I made a good choice.
If I have an issue with the OP's post it would be how about every dealer she's dealt with seems so disagreeable and aloof. Sometimes an approach (adjective) can yield success or disaster depending on one's personal tone. Even corporate? Something's awry. On the other hand, a new car with these many disabling issues can be infuriating. If you really want to have some fun, go to your fav Mercedes online forum and listen to those poor people. Sickening, and very common to hear someone driving home a $150k car that blows up on the way home. Like a tranny, engine, drive train, a/c doesn't work, electrical demons, lock-outs, instrumentation, you name it.
My first guess with the OP's complaint was similar to what some have already mentioned; a coil over, ECU or some other rudimentary ignition issue. I mean I read a bit into the post, but I'm hearing "screw you lady, we don't have time for you until December". Come on.
I know about every auto shop in the country is lacking competent staff with the root firmly in Covid, but anyone else get the feeling there's something missing here?
