Neat vintage Tonka dune buggy. With the hubcap wheels, I believe it to be from the early 1970's. Heavily playworn condition, bent roll bar, no steering wheel, bent axles. Wheels are decent.. good restoration project.
This is from the "Mini" series (not to be confused with the "Tiny" series), about 7" long and 4" wide. (About 10.5cm wheelbase)
