What scale and size is this Land Cruiser model?

It is 1/24 scale, roughly 8 inches long, 4 inches wide and 3.25 inches tall. That makes it a large shelf model, noticeably bigger than 1/43 diecast cars.

Does it have opening parts?

Yes. The hood, all four doors and the rear gate open, and the front wheels steer. The sunroof is part of the roof casting rather than a separate opening panel.

Is it a toy or a display model?

Both. The pull-back motor and rubber tires make it playable, while the diecast body and detailed interior suit display. Small parts mean it is better for older children and adults.

The model car in the manufacturer's original unopened packaging. No tools or batteries are needed, since the pull-back motor is built in.

How does it compare with premium 1/24 diecast models?

It offers opening panels and steerable wheels at a mainstream level, with some plastic parts. Premium ranges add finer engine and interior detail and tighter panel gaps, but usually cost more.
