I have never looked under the hood so I can't speak to that. The grille is different on the base. Good look in your search. The cloth interior has like a black and gray swirl to the seats in the middle. Base seats are not power and no heater in the seats. Maybe someone else can give some other things.
I have a base coupe. Pretty sure the back brakes are disc. But you are right... here are a few extra differences.
The base also has no tire pressure monitors, garage door openers, no cupholder (has the bin), seats are cloth with no power or heater. No cargo net. I think that covers the difference. To me the less gadgets the better... which is why I bought the base. Less things to break (like the heated seats) and really thankful there are no tire pressure sensors. Those things are a pain in the rear! I also preferred the cloth seats because every leather car seat I owned cracked in the Texas sun. I bought mine brand new in 2005 and the base coupe seemed like a better fit for me.
The exterior is black on all base cars... the side grills and windshield surround is black (no silver trim). Radio **** is black. Not sure about the shift ****. They all seem like the same silver color to me. The engine is the same... except the engine cover shield is black (not silver like the other models).
