The problem with Model S as I see it is that there isn’t enough difference in the car itself to justify the price against Model 3. I configured a new 3 and S with everything I’d want. The S was $97,000 the 3 was $61,000. If I had to make that call today I’d go with the 3 as I just can’t see $36,000 worth of difference.
I agree, the Model S is worth more than the Model 3, but not at that price difference. It's about a $10K more expensive car at best. I love my Model S, but if the Model 3 had been available, I would have bought one instead. It is much closer to my original price target.
The Model S dominated the large luxury car market for several years because it's a very small niche and a lot of people were drawn into the segment because they wanted that particular car. I would never consider any other car in that niche.
The Model S and X were helped at the end of last year with the last option to get free supercharging and the end of the $7500 tax credit. The Model S especially is a car layout that is becoming obsolete, in a size that is not terribly popular, even in the US, it's a design at the end of it's cycle, and it's overpriced for what you get compared to the M3.
If Tesla does do a refresh this year and rolls in a lot of stuff from the Model 3 as I expect they will (the first refresh was bringing a number of Model X features to the S), Tesla may be able to offer the Model S at a more modest premium over the Model 3 and still be highly profitable.
In the US, sure, most are down by not by as the S and X are down:
UPDATE 4-U.S. March and Q1 auto sales drop in weak start to 2019.
The first quarter of the year is always the poorest for car sales and the economy is softening. Expensive durable goods are usually the first segment of the economy to go soft when there is a downturn. People hold off big purchases waiting to see what the economy will do. Between trade wars and Brexit there is even more uncertainty in the mix.
IMO one of the two scenarios for Tesla failing at this point is a very bad economic downturn. The other would be a very big error on their part like the Model 3 getting known as the 21st century Pinto or something. At this point that probably isn't going to happen. Tesla should be able to surf a normal recession, but a repeat of 2008 could wipe out all 4 US auto makers.
