Just got my 2007 Acura TSX w/out nav last weekend. What a great car. It rides similar to my wife's 2006 Honda Accord but holds tighter through the turns and is more fun to drive. There is a little less room in the back than the Accord, but the front and the trunk space seems very comparable. The design is becoming a little dated and the redesign should be coming out some time in late 2008. If you love Hondas but want a little more luxury, then Acura is the way to go. Plus you can get a steal of a deal on the TSX right now.
Bluetooth, great interior lighting - the blue is easy on the eyes, intuitive and easy to operate controls, comfortable seats, and turn signal mirrors.
The sun visors don't extend. Even the 2006 Accord has visors that extend. Other than that, it's a great car!
