These have used and built! Details: - Lego 3-1 car racer: 1 piece missing (see photo of booklet). All pieces included and a few extra. Rarely, some substitutions for other colors. - Lego 3-1 space: complete set - Lego chicken coop: all pieces included. Rarely a few color substitutions. Not noticeable! Don’t have the box anymore. - Lego vet truck: all pieces included. I found the Frenchie after taking the original photo of the completed set (ignore that other small puppy, it won’t be included). House is smoke free and pet free.
