Despite tough competition, there simply isn't a better car for the money. I spent months looking at the competitors. The performance of this car will knock your socks off, it's just a thrilling car to drive. A test drive in the pouring rain sold it for me. The advanced electronics keep the car on track even when pressed hard in the rain, yet you feel totally connected to the road. The build quality is tops and Lexus has been attentive to every detail. It's a beautiful powerhouse, with the best navigation system out there. Everyone that gets in my car drools, it's just that nice. The paddle shifters in this car trump much of the competition as there are dedicated up and down shifters.
Engine - knowing you can take just about anything that pulls along side you, paddle shifters, Nav, VDIM make RWD feel like an AWD!, appearance, build quality, value, cooling seats, adaptive headlights, push button start, quality of leather, feel of steering wheel, stock sound system is amazing.
Audi's DSG transmission is still better. The 12 volt jack is positioned horribly in the center console. You'll need to buy a set of winter tires. Voice recognition could be better.
