One of the main reason for the purchase of this 'car' was the handling; It's really drives like a car that's been raised by about 8 inches off the ground. Wind noise is excessive at freeway speeds for a luxury car.
Overall design and exterior look.
Do something about the wind noise.
The fuel tank could be larger.
If Lexus is listening... Build it with a V8!! PLEASE!! Use 245's for the tires, the 225's feel a bit too 'loose'. Needs a larger/wider cargo area. Think MDX when you work on this one.
