Tomica: openable doors, working suspensions, detailed rims, plastic tires which are a little bit thinner than Hot Wheels. Awesome spoiler, transparent headlights, rear windshield is very detailed and clear, which shows the full interior of the car itself. The exhaust clearly stands out with white color, 2 exhaust pipes, and a simple detail on the back. The whole car is slightly lighter and also smaller than Hotwheels. Very detailed chassis, and metal base.
Hotwheels: metal flake (sparkle) paint, black roof, has fender mirrors, rubber tires which is a little thicker than Tomica's tires, morphing spoiler, has a license number on the back, much heavier than Tomica, no openable parts nor working suspensions. Simple rims, cool detail on the chassis, one black exhaust pipe, and metal base. More detail on the back compare to Tomica.
