I purchased my 2008 Acura TL Type S in April. 4 months later I am still very happy. Excellent acceleration and the gas mileage is surprisingly good. I've been averaging 27 mpg with city/hwy combined. Luxury and sport nicely combined. The TL offers more leg room for rear passengers than the IS 250 and G35. I wish the back seats were capable of folding down for my random stops at Lowes and Home Depot. The doors are hard to keep open while exiting but I will survive.
The navigation in my 08 TL is by far superior to my 06 GMC Envoy. The hands free kit is exceptional. Everyone says that I am very clear, I use it all the time.
Rain sensing wipers, ac vented seats would be a nice addition. The information display for the radio, time, and AC is impossible to read in sunny conditions due to glare - some improvement is desperately needed.
