The RCF design is actually already growing on me....
It's funny, 8 years ago my biggest gripe with Lexus was that most of their cars (with the exception of the 2nd generation IS) looked way too bland.
This one certainly isn't bland - I'll give them that
Now maybe 7 or 8 years from now they'll find a happy medium between too bland and too aggressive.
If the grill had a horizontal bar like most other cars that would fix a lot, IMO. That's why the only acceptable color for me would be obsedian black. Black would probably make the front end look less "gaping."
