WOW. What an upgrade. I owned a 2004 TL and I just bought a 2007 TL Type-S and I love it. It looks good, aggresive even. It drives aggresively as well. When you own a sports sedan you should drive like it. The F1 shift option is great. With close to 300 ponies it flies. The Brembo brakes are a plus. The car turns on a dime and it's just a blast to drive. It's a 9.5 out of 10 in my book. Buy it and you will love it. It has all the gagets inside: Navi, voice recognition, MP3 hook up, 5.1 Dolby sound, rear view camera, XM radio. I'm sure I'm forgetting some thing, but there's just so much inside you tend to forget to list all the goodies.
F1 paddle shifters, best sound system I've ever heard in a vehicle, very easy- to-use navigation system (i.e. If you're in the mood for Chinese food, say it and you're there).
