While this may be true, they still have to understand that many of the limitations they impose on their models prevent the cars to express said individual character.
A random example? AVS suspension limited to F-Sport trims only, aluminium pedals limited again to F-Sport models, a specific design of rims (not always --> see UX) for each trim that you have to like even when it comes to the dimension otherwise you have to pass, forced NuLuxe without the possibility of picking real leather as a paid optional, Mark Levinson only on highest trims, etc..
I like Lexus, otherwise I wouldn't be here, but lately the competition has been making good alternatives while offering a more sensible amount of customization to their vehicles. I'm thinking about Volvo for instance.
Ps. Is there a need to even mention out of date infotainment system which is everything but user friendly? Every single reviewer on earth agrees about this but so far Lexus and Toyota did nothing to make the system better, instead they threw out random pheriperals to control the system without being coherent (mousepad, trackpad, stick, etc..) on the whole lineup, so every car has its own system...
