Yea, I know the engine bay is dirty, but I figured that was mainly cosmetics. I think they may have skimped on some maintenance stuff, but the main thing they had reciepts for oil changes. Of all the things you can do to a car, that has to be the most important. I can clean things up on my own and replace air filters, fuel filter, etc. easy enough. Replacing engine internals because the oil was neglected is not so easy.
