Owned four Acura over the years - all were great. Bought this TL and have put over 150,000 miles on it. Its a classy looking car w/o being over the top. Its amazing that the car is over 10 years old and people think its a newer model. Acura created a design with some legs on it - it stays contemporary looking well beyond the norm. Only repairs in the last 10 years is a new starter(very expensive $600) and new rear calipers. Everything else has been normal wear and tear maintenance.
Quality, Looks, Handling, exclusivity (you don't see these cars at every stop light)
The newer TL addressed my concerns: Quicker Throttle response, Larger tires, bigger brakes, and more power. Although I am not as excited about the new TL's styling - but that's personal preference.
