Product Review (submitted on July 1, 2013):
This rig really is big! So big that it fits 44 die cast cars (like hot wheels or matchbox cars). It opens up on both sides, and each side fits 22 cars. My 5 year old son has a huge collection of these cars, so this was an easy way for him to roll them all "around town". It's build super sturdy, the wheels roll awesome, and he loves it. Great purchase!
