This is my very first post to TMC, but I have spent the last month reading and reading until I feel somewhat smarter from all you wise Tesla fans. I am planning to get my own S 85D and decided to ask about inventory cars that match my top requirements (which are tech package with autopilot, pano roof and AWD). My local Tesla team found one with 413 miles that matches all those and which has some other things I want and only one I don't care about (sub zero weather package - I live in Houston!). This care is $6000 less than its factory list. Is there anything special I should ask before going for it? I want to make absolutely sure I get a 2015 with all the current hardware that exists to enable autopilot features as they come down the road with software upgrades. I think if it's quoted as a dual motor with autopilot that must be the case, right? Here are the full specs: P73158 List Price 100,970 Discounts 5,462 Purchase price 95,508 Odometer 413 85 kWh Battery Autopilot Dual Drive Motor Black Solid Paint All Glass Panoramic Roof 19" Wheels Grey Nappa Leather Seats Obeche Wood Gloss Décor Tech Package Smart Suspension Fog Lamps Black Alcantara Headliner Subzero Weather Package Includes heated steering wheel Parcel Shelf 19" Michelin Primacy Tire Upgrade Dual Chargers Thanks in advance for your advice!
