I have a history of trading cars I like for the same model if a significantly higher-powered version comes out. I did it when Mazda added a turbocharged 1987 RX-7 to its lineup a year after I bought the new generation 1986 RX-7. I did it when Mercedes added a 2004 supercharged SL55 AMG a year after I bought the new generation 2003 SL. I did it when Audi brought out the 2010 V10 R8 two years after I bought the new 2008 V8 R8.
The only car I kept after a more powerful model was introduced was the 2015 Tesla Model S P90D. That car's performance was so far beyond what I could safely use that I just no longer saw the point.
This leaves me with a dilemma regarding the Air. Even before I received our Dream Edition Performance, I was assuming that I would trade up to the tri-motor Air when it arrived. However, I'm even more of the mind than I was with the earlier Tesla that the car has such prodigious performance that there would really be no point. Also, after now experiencing the deleterious effect of a rearward weight shift in the Model S Plaid due to the additional rear motor, I'm concerned the tri-motor might even be a step backward (although its motor is considerably lighter than the Tesla's in a car that weighs several hundred pounds more overall).
That being said -- and as there is nothing on the horizon for the next few years that promises to compete with the Air in its superb balance of performance, comfort, and style -- it may be the car we keep for a while.
