I bought my 03 TL new. The good: under my ownership, I loved the car. The navigation is still among the best and the seats were very comfortable, even during my OK to CA road trip. The traction control kept me safe in the snow (people from San Diego do not belong on snowy roads!) and saved me from possibly killing myself on the highway. The bad: TRANSMISSION!! Acura will only replace the transmissions for specific failure codes which means many of them are no longer being covered under warranty. If you can't afford the expense, stay away! Stay away! Stay away!
Navigation, interior styling, safety, comfort of ride.
Acura needs to step up and replace ALL transmissions during these model years. Go with the 04-08 model.
