I know well these cars, but I'm not sure that it the fact that the rear looks different from the 5-door version qualifies it automatically as a coupé. I don't where to put the limit between a 3-door hatchback and a coupé with a hatch.

This is a coupe with a specific body (rear modified), unlike the Xsara.

Yes 😀

So you mean replace hatchback by sedan?

Class: Cars, Sedan except for Cross Turismo, Sport Turismo and Prototype

Yes Taxi could be in the name too.

Done
Maybe Taxi should even be in the name too then?

I think "Hybrid" should be part of the model name for the 2019+ Toyota Comfort (HK version). Toyota Hong Kong website lists it as the "Comfort Hybrid Taxi":

Also, according to this article, it wasn't introduced in HK until January 2019:

So I think year should be changed from 2018 to 2019?

@JB007 > wasn't there a discussion about these? Aren't them rather 3-door hatchback? Like the Xsara Coupé.
Though that Wikipedia mentions 3-door coupé as body style.
If nobody is against that, I can update them, but I'll wait a few days just in case
I'll already add the extra info "Coupé" for those that do not have it yet.
