A 544-piece Technic build of the Shelby GT500 drag car for ages 9 and up. Two pull-back motors send it racing, and the LEGO AR+ app adds timed races and challenges on top of the build. A rear cover turns it into a display model when play is done. It sits between simpler pull-back Technic cars and the larger, pricier Technic supercars: fewer pieces and no gearbox or steering, but the same look and a quicker build. Owners rate it highly and call it a fun, sturdy build; some find the pull-back play and AR app thin after the first few runs.

Buyers rate it 4.7 out of 5 and mostly praise the build and the pull-back racing. The common complaints are that the play value is short-lived and the AR app is a gimmick for some families.
