polish the top of your engine, won't cost much... get all the little metal hoses, clamps and bits zinc coated and chemically polished... there's places that do em in bulk for a couple of hundred bucks, and they come out shiny as. cover up your electrical bits and give your whole engine bay a good hosedown with grease remover that they sell in autobahn, don't get it on clearcoat, but on any other paint its OK and the grease n dirt will wash off. after that just tidy up your wiring and put all the polished bits back on and you'll have a nice engine bay.
