i am a manager for a honda dealership and there are alot of accesories available even through honda. depending on what you want to get for it there are plenty of aftermarket accessories available also. alot of dealerships like my own also provide accessories that are non factoy like exhaust and things and if you buy them through the dealership the dealership will usually cover it in there own warranty. the dealership i work for will put a 2 year 24 k warranty on the parts and service your car without avoiding your factory warranty
