I will hopefully be buying a new Niro PHEV EX soon, and was wondering what advice people have for negotiating with Kia dealers and the various upsell techniques they'll inevitably try. My default position is to refuse the extended warranty and decline all upgrades (except the cold weather package, since I live in Minnesota). What kinds of upsells will dealers try to push on a Niro PHEV, and are any of them worth considering or negotiating over? (I'll be going in with a pre-approved loan from my credit union and lots of data for what that would cost per month and overall — the usual advice. I'm interested in being prepared for Niro-specific add-ons that I'll get swarmed with.)
