I'm slowly listing all of the 100+ Hot Wheels (all original Redline) that I had as a kid.  All were gently played with (except for a few that my kid sister got a hold of, sigh).  I combine shipping if you buy more than one.

Early US version based on the clear glass.

My observations:
Base is shiny with a little tarnish.
Some edge wear to paint.
Engine hatch opens smoothly and stays up.
All 4 wheels spin freely, no wheel suspension issues.
