You mean 3.
Ya I agree. Lexus is one of the most common luxury cars in America. I see them around in LA a lot more than, say, Audi (Obey in GTA). In fact I see them just as much as ,BMW and Mercedes, and both brands are represented by a ton of cars in GTA. They should certainly have more cars than just 1 model in GTAV.
Sultan is a Lexus IS300 1st Gen/ Toyota Altezza 1st Gen.
Habanero is a Lexus RX 2nd Gen.
And the Asterope is a Lexus GS/Toyota Crown.
But they are branded as "Karin"
I think the Asterope is a Camry. Its just that Toyota does not do a good job of differentiating styling between their Lexus and regular Toyota branded cars. The Camry and GS do share a similar shape so I could see your argument. But when you go online to buy an Asterope, it costs only $26,000 and is described as an "Attainable luxury", which sounds more like a Camry because a late model Lexus would be a lot more expensive. Plus, if you look at the c-pillar, it becomes clear that it looks more like a Camry than a Lexus.
They should make a clearly distinguished Lexus like the LS. Even the LX (direct competitor for the Benefactor Dubsta) would be nice. Even an older school LS (Toyota Celsior) would be nice. Or bring back the Lokus. But like a few other brands, Lexus is a very popular brand that is underrepresented in V.
OT, but Looking at all of the cars and DLC cars, it becomes clear that Rockstar is too focused on European cars. Not enough variety when everything is euro. Lots of overlap of Euro cars, particularly luxury cars. If they eanted to make so many euro cars, they could have given us a VW Golf GTI or something for the compact class. But instead, everything is luxury based which gives us no variety.
