if i remember right the cats are stupid money for this car. but thats gonna also bring the value down a lot when it comes time to sell.
so do this, buy the parts, get your hands dirty because none of that is difficult work, or do what girls normally do, find a guy, flirt with him, have him do the work for free because he thinks hes gonna be able to touch your tits, only contact him when you need word done on your car.
