DD does but she has always been really good about not putting things in her mouth. She loves the Littlest Pet Shop right now and keeps the tiny pieces away from DS.
DS plays with the Playskool/Tonka cars - the ones that you can squeeze. I will sometimes let him play with matchbox cars if I'm playing with him. He still puts almost everything in his mouth.
Re: Do any of your kids play with small toy cars?
dd plays with matchbox cars daily(always under supervision though!) She loves them.

My 2yo loves them and has played with them for many, many months. Certainly before last Christmas when he was 18 months old.
