I figured I'd register after reading through this thread - We have a Tesla Model S P85 and BMW i3 Rex in the garage. The Tesla is my daily driver, including snow tires for winter. Each vehicle is different and has it's advantages (the i3 LED headlights are amazing!), but I like both of them and don't mind switching cars once and while.
I absolutely love the Tesla, and think it was worth the money. Acceleration and regen is strong and smooth, and I've had very few issues with the vehicle after a full year. Besides the collision ones you've seen, there should continue to be some pretty good CPO deals coming in. With the P85D coming out recently (all wheel drive), a lot of people traded in their rear wheel drive ones to upgrade. There might be more of that once the Model X starts to ship. Or watch the Tesla Motors Club forums for sale posts - there have been some decent deals on there too. And to the point of the Model 3 (will be looking at this once the i3 lease is up), I wouldn't be surprised with a delay into 2018 after watching the Model X.
After driving these and enjoying the 1-speed and quiet smoothness, I test drove a 2014 S and 2015 SR. The SR will be picked up this Friday.
