Actually I surprised a few buggy racers when I showed up to a local track and I had the only monster truck. They let me race against sportsman 1/8 buggies and I was running in 5th out of 10 when I broke a rocker post.
That said the pro 1/8 buggies were running 4+ seconds faster per lap than me. I know if the buggies I was ahead of were setup correctly with a decent driver that I would have stood no chance.
