What's the "3, 5, 7" of major car brands?

You forgot:

Nissan, Infiniti (Nissan also has trim levels S, SR, SV, and SL)

For the longest time I erroneously thought Infiniti was Mitsubishi’s luxury brand; I guess it was all the "i"s.

For Jaguar, it goes XE, XF, XJ from bottom to top and they correspond pretty closely to 3, 5, 7 respectively.

For Volvo it used to go S40,S60,S80/90 but nowadays its more xc40,xc60,xc90 as they focus on SUVs.

Dont forget the CX-7, sold from 2006-2012. I would think that a mid-sized crossover would be attractive today, against the new Honda Passport.

There’s also a China only CX-4

Sold strictly with the model name, no Buick, which they will begin here as well.

That article actually seems pretty vague " Buick apparently does not put the Buick name on its cars in China either."

Whereas you can look directly at Buick’s site in China

The url, obviously, and site contain the name ‘Buick’ in Latin letters, there’s a picture of a dealership building with the name in Latin letters, the site repeatedly uses the phonetic equivalent in Chinese characters, 别克 (biékè), and the cars shown all have the ‘three shield’ logo.

Buick has a distinct brand identity in China dating from even before 1949. I recall a WSJ article in the last several years about that though I can’t recall the exact date. It’s definitely not an unknown brand which was never introduced there.

There might be some shred of truth in the statement by the journalist, like maybe they don’t emphasize ‘Buick’ as much as in the past or in some other particular ad, or the letters ‘Buick’ aren’t on the cars as much or something like that? But it seems at least significantly incorrect or garbled.

If you’re going there, then Biscayne < Bel Air < Impala < Caprice, from '66 to '72.

I’d say the lineup is

Fit
Civic
Accord

That’s not quite accurate, though. You can’t sell it without the Buick name; that’s the brand. I mean, we do the same thing here with well-known brands: You don’t have to qualify “F-150” as “Ford F-150”; everyone knows what it is. Buick models are definitely sold as the Buick brand in China.
