>>10059283I would check into Chap Mei vehicles on Egay for good quality budget vehicles (and 4" figures to drive them).
Also hit up the toy section of your local thrift stores and haunt garage sales/flea markets; I have scored a variety of good vehicles very cheaply this way and sometimes you can find real gems for pocket change (I have found old gi joe vehicles, TMNT, MOTU vehicles etc.).
Also if you have a dollar tree in your area, they sell an exclusive line called Final Faction and you can buy an armored dune buggy for a few bucks and the figures are a buck twenty five. Also they have an alien vehicle that is more like a sci fi chariot thing that is rad as hell. I highly recommend checking out Final Faction - it's the sweet spot for collecting cool toys on a limited budget.
Good luck, happy hunting and welcome aboard the plastic crack train!
