Beautiful build quality, exceptional features. I am a sports car owner/driver, and I find it interesting that this car has made me change my driving habits as I strive to maximize my efficiency. If you want maximimum mpg performance this is a must, and it leads to safer driving habits on the road also. Having said that, it will get up and go if you romp on it. Typical Lexus luxury. Also, ignore recomendation for premium gas, 89 octane works just fine with no appreciable loss in performance or mpg.
Clean clean clean. Go green.
LI-ion batteries when available. Needs to use more composites to lose some weight.
