I'm looking at a car listed for sale across the country by a non-Tesla dealer as an 85D. Carfax also shows it as a 85D. On both the dash and touch screen the car says P85D. Anyone experience this before? I've read to trust what the car says it is on the screen. Is that 1000% bulletproof? Really don't want to somehow find out after purchase that is a 85D rather than a P85D. Thank you
