I currently drive a 2016 M3 competition and have been thinking about replacing it with a new Model S LR. This would be quite a change so I'm having trouble making a decision. I'd love to hear pluses and minuses from others who have made a similar switch. The other big question is timing. Even Elon Musk seems to admit that the first six months of production may not be the best time to buy a new model Tesla in terms of quality issues. Do you think it's too soon to buy the new and improved Model S? I'd especially appreciate hearing from anyone who has one of the 2021 models. But even if you don't, I'd value your thoughts based on experience with the brand. Thanks.
