The collectible die-cast Mach 5 is a definite improvement over the round tin case from volume 3. It is pretty durable and measures 3 3/8" long x 1 3/8" wide x 3/4"high. The only moving parts are the wheels/tires. It rolls forward very easily but has trouble rolling backwards. The interior is painted red (as it should be), and you can see the steering wheel, two seats, and stick shift. The steering wheel, however, has no buttons (too small). In addition to the headlights, you can also see the outlines of the two doors, trunk, homing bird hatch, and periscope hatch.
The height and width of the outer box matches the same dimensions of a standard DVD case but is almost 1 1/2" deep to accommodate the die-cast toy.
The DVD begins with four previews, which you can just skip (run times in minutes:seconds):
Ultimate Avengers The Movie 1:55
Dragons Metal Ages 1:47
Inspector Gadget's Biggest Caper Ever 1:13
Pinocchio 3000 1:59
All four are either 2D or 3D animation. Beyond the previews, I found no other DVD extras, which is why I gave it four stars instead of five.
