"The Go-Kart Racer polybag earns its Recommended BrickScore of 73.5 as a standout example of what a small promotional set can be: an exclusive printed element, a unique minifigure, and perfect synergy with a larger set in the range, all for under four dollars."
Reviewers agree that the Go-Kart Racer polybag punches well above its weight for a small promotional set, with its exclusive printed 2x2 curved slope being an unusual bonus for a recruitment bag. Brickset called it close to the ideal polybag, pairing it perfectly with the larger 60400 Go-Karts and Race Drivers set. Owner ratings are extremely positive with all 3 LEGO.com buyers giving it 5 out of 5, though the sample is very small. RacingBrick was somewhat less effusive, noting the build is simple and less exciting than other polybags in the same price range.
Where they split: Brickset is more enthusiastic (calling it nearly the ideal polybag) than RacingBrick, who is positive but notes the build is less exciting than comparable polybags. The difference is modest and both recommend it.

"30719 Go-Kart Racer manages both, so this is pretty much the ideal recruitment bag, in my opinion!"
Brickset Reviews"The exclusive minifigure parts and the compatibility with other City racing sets make it a decent little addition."
