Roll Cage was Mark Barthold's first and only design. Mark worked for the brand designing many of the outragous and innovative toys under the Hot Wheels umbrella including XV Racers and most of the flying toys of the late 90's and early 00's. Note: The Roll Cage has the same spare Off Road Saw Blade tire no matter what the main tire type is. In 2010, a casting change resulted in the removal of the spare tire. In 2013, the casting was changed again; the metallic side panels were now molded as a single piece with the body, instead of the metallic side panels being a part of the base.
