Acura TL - Good choice
I recently replaced my 1988 Honda Accord (182K miles) with a 2001 Acura TL. Check the owners manual regarding the break-in procedure.
I change the oil in my 1988 Accord at 500 miles, 1500 miles, 3000 miles, then every 3000 miles with Valvoline dyno oil. When I retired the car with 182K miles the engine ran like new.
I would also recommend frequent transmission fluid changes - use only Honda ATF.
