I would assume that you're being respectful whether you said it or not ...
Don't get me wrong, I'm not saying that any other vehicles do this. My ideas are a step towards excellence and market domination.
Engine compartment: Engine block cover looks like they wanted to build a one size fits all and they should stop using metallic paint; it adds nothing. It would have looked a lot better if everything was completely covered, in black, and only certain parts were exposed; fluids only for example.
Interior:
That black frame surrounding all the displays. Why? This is 2015. Frames are ugly. What's worse, it's beveled.
All the chair supports, etc.. black plastic which doesn't conform to the shape. If you're going to use plastic, it should not be obvious.
I'm very picky, I know. I just want Lexus to build a car that people just can't wait to buy. Look at the new Volvo XC90; there's a waiting list for the car. It may be due to short supply to make it seem like the car is heavily demanded but at the end of the day, it's a home run for Volvo.
