Just passed 4 years with my S85. I used to be a regular here in the lead up to buying and in the several months after delivery of my S85 but haven't checked in much over the past couple of years. Just passed my 4th anniversary on March 10 and the car is as good, probably better, than the day I got her. Only regret is not getting the sunroof (pretty buggy in the early days) and seat heaters (only came with the leather seats). I've had a few problems over the years, but nothing too annoying and everything quickly remedied by my service center in Raleigh, and never a single grumble or complaint about the 2.5 hour drive to come pick up my car. My current set of tires has about 20k miles but the car feels as smooth as the day I drove it home the first time. I had a P85D loaner for my last service visit and it was a blast with the power and the autopilot, but I was happy to get mine back. The old cloth seat (still in great shape) is more comfortable and the car feels smoother and quieter than the loaner. Thanks Tesla!
