The Model S is totally unimpressive compared with the Model 3 in terms of design and build quality. For example, the Model S still uses the same tail lights w/ discreet LEDs from 2013 versus the modern LED light pipes in the Model X and Model 3. Model S has the worst headlights of all three cars, rated "poor" after extensive IIHS testing. I recently test drove a Model S P100D, the steering rack vibrated tremendously with the A/C running. This is a vehicle Tesla uses to sell customers on the brand and in 5 minutes I could tell it was subpar compared to almost any other manufactured vehicle.
Tesla's priorities are screwed up, in my opinion. They are more focused on video streaming and in-car game play than they are with things that matter to the majority of consumers. You know, little things like a steering rack that doesn't shake. I was all in on Tesla 6 years ago, a few years before Elon Musk completely lost his mind. Service quality has declined substantially since the early days to the point where Tesla is denying legitimate warranty items and forcing owners to go to arbitration or file lawsuits.
If I were in the market for an EV and had north of $80,000 to spend, I would certainly wait for the Mercedes EQC. My next EV will very likely not be a Tesla, and this coming from one of their biggest fanboys a few years ago. Tesla suffers from extremely poor corporate leadership resulting in poor execution across the board.
