We used to play with cars, but I know that my experience was more one of making up stories about the people who USED the cars, rather than just driving them around and making "vroom vroom" noises.
My brother wanted to play Barbies with us. Unfortunately his idea of playing Barbies was that you take all the clothes off, rip the heads off, drive over them with your Tonka trucks, and inform your by-now-irate sisters that Barbie got run over 
Consequently we gave him his own Barbie. It was about the ugliest Barbie we owned. She was very old, parts of her legs were broken off, and she'd been scribbled on with a marker. He didn't seem to mind, thankfully.
