Anyway, my '01 Acura TL is still like new and I am going to put some money into maintenance items and keep it.
My suggestion is to keep up the maintenance on this car as it's not even at half it's life! If you are serious about someday replacing it start banking the money you would be making on a car payment now and by the time ( a few years from now) you need to replace your Acura you'll have an advantage over the sales person if you can put down a hefty cash amount or better yet pay cash for your next car!
