x2.

I'm going to look into a grill block (for the lower grill-- the top one is actually a solid piece of plastic with no slots, and blocking the middle would probably not do the engine cooling any favors for the summer) and partial front undertray/air dam (it makes sense in my head, I swear), as soon as I have the cash for a sheet of coroplast or the equivalent. At this point, I get better mileage in town than on the interstate, which is sort of messed up.

Maybe some day, a full pan on the underside-- I think I can do it in steps, front to rear. The part that has me flummoxed is the rear axle. I would really hate to have it interfere with a pan, if say, I jacked my car up.
