As I recall, the original Bondi blue iMac was the best selling model of personal computer at the time. This wasn't because Apple suddenly stopped being the Betamax of the home computer world, it's because there was only one model when everyone else had a full range, and the effect disappeared the moment they came out in multiple colours.

Same deal with Tesla: They have two core models (Y top, 3 next, all else a rounding error), while everyone else has a full range that sales are split across.

Of course its relevant as Tesla is valued to much more than the other makers despite selling in total fewer cars.

Tesla is indeed a niche maker, but their valuation does not reflect that fact.

We’re not discussing valuation we’re discussing model sales?

If I want to buy a four-door Toyota sedan, I could buy a Prius, Corolla, Camry, Crown, or Mirai (not even counting Lexus or Century models), diluting each model's car sales, while overall vastly outselling Tesla. Ditto for cross-overs, SUVs, etc.
