Our verdict

This Mattel Brick Shop set builds a 1:16-scale Corvette Grand Sport race car from 918 pieces, for ages 10 and up. It comes with metal wheel covers, a decal sheet, a signature plate and a matching 1:64 die-cast Hot Wheels car, and the hood opens. Mattel Creations lists it at $54, and Mattel says the bricks work with other major brick brands.

At Target it averages 4.1 from 91 ratings, with split opinions. Some owners say the printed parts and fit rival pricier LEGO sets; others found connections loose, with exhaust pipes and bumpers popping off, and one 10-year-old could not fit the front wheels.

It suits a 10- to 12-year-old car fan who wants a display model and can work through tricky steps. Skip it if your child is younger or easily frustrated by loose pieces.

Paraphrased from public owner reviews. Each one links to where it was posted.

Positive
Bought it on sale thinking it was LEGO; the piece quality, fit and detail rival pricier LEGO sets, with printed windshield and rear window.
Target customer reviewDec 1, 2025
Mixed
Turned out great, but tough for a 7-year-old with unclear diagrams; some connections are flimsy, so exhaust pipes and bumpers pop off.
Target customer reviewApr 4, 2026
Negative
A 10-year-old had to stop at the front wheels because there was not enough room for them, and the pieces did not hold together tightly.
