It is almost 4' x 4' and there are over 320 Hot Wheels cars of which about 95% are easily recognizable to car people and many BMW's. The original plan was to only use BMW's but I soon realized it would be impossible to collect that many. All of the cars between the B and the W (including the letters) are BMW's and many of the blue and white cars along the edges are BMW's with some more in there too.
