This exclusive Costco bundle includes two Mattel Brick Shop Hot Wheels building sets: the Elite Series Corvette Grand Sport (918 pieces, 1:16 scale) and the Speed Series Cadillac Project GTP Hypercar (236 pieces, 1:32 scale), totaling 1,154 pieces combined.

The Corvette Grand Sport recreates the legendary race car of which fewer than 130 originals were ever produced. This 1:16 scale model features authentic fenders, metallic exhaust pipes, an opening hood and doors, custom decal sheets, and a choice of Hot Wheels-designed or American Racing rim covers. Each set includes an exclusive matching 1:64 scale die-cast metal car and a metal signature plate.

The Cadillac Project GTP Hypercar is a 1:32 scale buildable model featuring the modern endurance racing prototype with faithfully recreated aerofins, opening doors, custom decals, and two sets of interchangeable wheel covers. It also includes an exclusive 1:64 scale metal car and signature plate.

Both building sets are compatible with other major brick building brands. Recommended for collectors and builders ages 10 and up.
