Is this a mainline or a premium Hot Wheels?

It is a Boulevard release, the collector-oriented line with metal bodies and rubber tires rather than a basic mainline car.

What scale is the Bronco?

It is 1/64 scale, the standard Hot Wheels size, so it fits alongside other Hot Wheels and similar die-cast cars.

The card back carries international stickers, a detail carded collectors check because it differs from US-market cards.

It works, but Boulevard cars are built for display and collecting. A basic mainline Bronco is the cheaper choice for rough play.

It is 1/64 scale like other Hot Wheels, but Boulevard models are aimed at display, so track use is not their purpose.
