I collect only Jeeps. I have more matchbox than hotwheels, as matchbox seems to routinely come out with jeeps. Hotwheels rarely does.
I do also have several johnny lighting jeeps too. I buy them when I see them. Another company I recently found is greenlight. They have several jeeps as well. I have a couple other random brands and models, but nothing major.
My collection is 95-99% jeep. The rest is a handful of AMC javelins hotwheels came out with several years ago.
