Get better shocks, adjustable shocks that will give you a really soft ride. Depending on what wheel size you have you could upgrade to a larger brake disc and do a rear disc swap. (A 17" rim would easily house 13" brakes, if you have the 15s you could swap in 11" discs. I know for the 94-97 Accords the V6 and wagons had 11" rotors.) Aluminium trim looks tacky, if you want to go upscale looking get wood grain. Paint the moulding to match the car. Get better tires for less road noise. Get a better audio system since you drive a lot.
