Instructions on how to get final coordinates at the bottom.
I have been going to this cars and coffee since I was about 3, maybe younger even! It is seriously one of my favorite things EVER!!! I love seeing cars from off-road German cars, British overlanders, to tiny little French sedans!
I have hidden this cache on the infamous "British Car Day". I spotted one of the first "DAF"s in the United States which is a personal favorite.

WP1 will take you to a tree that has a metal number plate (like a license plate!) that was put there from before. Do the math below for final coordinates.
