I have a box of Hotwheels track with some cars for sale. We bought this set from Costco about 8-9 years ago. I think it was an exclusive product. It's a large plastic box with the Hotwheels logo molded into it. It came full of Hotwheels track including loops, superchargers (I think 4) etc. There's 3-4 cars to go with it (one never opened). My son says he'll toss in a large container full of die cast cars (mixed makes). The box lid hinge is broken.
