Several months into my new-old car. Left - as bought. Right - an hour ago.

Plumbing is more plumbed.
Shiny is closer to actual shiny.
Gasoline is closer to being vaporized.
Black is closer to black.
Rubber hoses are closer to being rubber.
Coolant is no longer just water.
Crankcase ventilation is MUCH closer to being positive.
Engine oil is closer to being strictly internal.
Red is closer to red.
Cabling and wires are farther away for the original 'tissue paper strength' additions.
Bolts are now actually, you know, bolted.
Am I done? Not even remotely.
