When I was looking for a new car, I compared the G35, IS 250, Toyota Avalon, and the TL with each other. The thing I really liked best was that the things I really wanted (multi-CD changer, moonroof, leather) all come standard with the TL. I have had the car now for 3 months and I am really enjoying driving it. Although not as much horsepower as the S-Type, it is the most powerful car I have owned. I'm surprised I have not been pulled over yet. This is the first car I have owned that I have hit 100+ MPH with! I love the interior of the car with the black leather pretty much throughout. I like having the audio controls on the steering wheel.
Just the overall exterior and interior looks. I can see having this car for 10 years and not feeling like it will ever look dated. I love the leather seats and the stereo is very good.
I would bump up the HP of the basic package to get closer to say, a G35. I have 260 HP vs. 305 for G35.
