2020 Raptor

Always wanted one, and now have a shot. 2020 802a magnetic 50K miles…when I go to the dealership, what should I be looking for and testing to ensure works? Any issues with this model year? It’s a ford dealership, ford certified pre owned, looks 100% stock and very clean, at least from the pics. I’d most likely buy the longest ford warranty they’d sell me, unless otherwise discouraged (by y’all). Thanks in advance. Coming from a 2021 ram rebel, which is my only non-ford vehicle ever for the last 30 years.
