I have a promotional McDonald's child size battery ran vehicle we won back in the 90's. It is in great shape and we would like to sell it but have no idea how much to ask for it. I cannot find another one like it on the internet... I need help!

Do you mean that this is something that a child would ride in? Is there a specific name for the toy vehicle? If you know the name, then eBay is a good place to look for things to get an idea as far as the price.

I did find sites with, I hope and am assuming at this point, similar items to yours by doing the following search.
