I've personally not heard much about reliability (maybe a bit about sticking door handles), although I do know that if you're in an accident, it can take a while to get them fixed. I've been in a couple of Model S' and didn't notice any glaring quality problems, and I can't lie, I was blown away by them. My car simply felt like something out of the Victorian era after the experience, and I'm not joking, it look me a fair while to switch my mindset back to liking the internal combustion again.
I know they won't be everyone's cup of tea, (or within budget) but when I go to EV, I want it to be a next gen experience. I don't just want a car like I have now, but with an electric motor. This is where I feel Tesla have it right.
The handling on them is also pretty good due to the center of Gravity, and yes, the performance is focused strongly towards acceleration but we're only talking above illegal speeds where other cars can take them, so for road use, I'd rather have some fun and legal acceleration than a fast 100-150 time. And that acceleration really does have to be experience to be believed! The one I went in was 0-60 in 3.2 and that messed with my head, and the same with the driver. I do wonder if 0-60 in 1.99 is actually safe - can you really stay in proper control of the car with that level of g-force?!
