The only difference is the 60D has it's range limited to to 210 miles to preserve the batteries. This car can be upgraded to the 75D at ANY TIME by a simple software update from Tesla. For those not familiar with Tesla, the 60D is EXACTLY the same as the 75D Heated Seats
Here's a detailed list of the features and upgrades: Model S 85D All-Wheel Drive Pearl White Multi-Coat Paint All Glass Panoramic Roof 19" Wheels Black Next Generation Seats Piano Black Décor Matching Yacht Floor Black Alcantara Headliner Supercharger Enabled Autopilot Convenience Features Premium Interior and Lighting Smart Air Suspension Subzero Weather Package Outdoors car cover Free Supercharging.. The only reason I'm selling it is because I purchased the Model X, otherwise I would keep the car. I added a clear bra and Evo Quartz protection to protect the paint from road debris
