It's a Mercury, to be exact:
But there's a bit of a mystery: apparently this type of Matchbox car was made only between 1955 and 1968. Our house was built in '78. Hmmm.
Anyway, it was manufactured in England, and has seen some pretty rough times by the looks of it. I think it's fabulous, all the way from its faded lime green body to its little molded plastic passengers: two happy canines peeking out the back.
It already had a bath via the garden hose, but after a sounder scrubbing it's going strait into a display case. I dare you to prove that you found anything cooler under your house today.
