What Color Engine Bay?

Oh I don’t know, most people won’t get over the rusty exterior to wonder what under the hood looks like.
I can imagine seeing it parked at a show or cruise, sitting with the hood up. Walking up to it, you couldn't help but wonder what he could be showing off under there to have it propped up. Anticipation would build. Then BLAM!!! That's the effect I was thinking of. A pleasant surprise hidden under it all.
