Query: Made a mistake with this toy

I bought these cars for my nine month old thinking she'd like to roll the cars along the floor and nest them inside each other. She only liked the smallest car (and for only a couple of minutes) which was easiest for her to pick up and rattles, unlike the other vehicles. She hasn't looked at them since the day I bought them so they have been given to her grandmother in hopes that she'll find them more interesting later on. The vehicles don't do anything besides roll IF you push them (they won't roll on carpet if you don't continue to hold onto them and push). The idea behind this toy is good but I didn't think they were very fun either so I can't recommend this toy. I think the box for this toy said six or nine months and up, but I think perhaps it is a better toy for older toddlers, not babies.
