The 2025 Heartland Model Car Nationals will be the 33rd show put on by the KC Slammers Model Car Club based in Kansas City, KS. Our 2024 show had 637 models entered with over 95 entrants and 87 vendor tables with tons of model car kits, aftermarket parts, tools, etc. for sale. We have 28 separate classes and 15 Master Awards, including the Heartland Champion award. The Overland Park Convention Center, Overland Park, KS is a great venue with plenty of parking, nearby restaurants and lodging. We create a PowerPoint-based awards show with photos of the Class winning and Master Awards winning models along with the entrant's name and class sponsor. It is simply a great show put on by fellow car modelers and we even have a class called "Military (automotive related)…any non-track, automotive-style vehicle used by any military force from any nation." for our fellow military modelers. We're almost dead center in the middle of the U.S. Our 2025 theme is "Dad said “Noooooo!" Here’s the deal…Do you remember that first car that lit your fire that you could purchase with lawn mowing money? You had the money and you just needed Dad’s blessing…but DAD SAID NO! Build the model, tell us your sad story in a few sentences, place it by your model and bring it to the BEST Model Car Show in the Midwest. If you haven’t been to a Heartland Model Car Nationals you just haven’t been to the best model car show in the U.S. We work very hard to put this show on and it’s an “all-hands-on-deck” operation. We hope you’ll join us. YOU WON’T BE DISAPPOINTED!
