By that, I mean - is it clean enough that you can read MOWOG on the parts that say MOWOG, that you can read 1800 on your engine block (assuming that's the engine you have), that you can change the spark plugs without getting piles-o-gunk under your fingernails???
I'm asking because whoever owned the GT before it was rescued from the impound lot should be strung up and allowed to die a slow, painful, crudded-up death.
Oh.My.Gawd. That engine and engine bay were the NASTIEST I have EVER seen. EVER. I spent six hours with Awesome cleaner & scrub brushes, cleaning up the peripherals & some internal parts; alcohol and another degreaser for other parts, and helping (before the cleaning) to remove the engine from the car. I wore out two wire brushes, went through a gallon of cleaner, half a gallon of alcohol...
If your engine bay isn't clean (I don't mean show-quality spotless, I mean FUNCTIONALLY clean), GO CLEAN IT NOW. You don't want ANYONE to come along behind you and call you everything I called the GT's DPO. (His name is now "Mr. Disgusting T. Gunkmeister," and I can only imagine how his house looked if he let the car get to that point.)
Seriously. You'll be doing yourself (and whoever takes over your car when you're done with it - however that may be) a huge favor. You'll at least be able to do your maintenance without having to bathe in gasoline afterwards.
