Checkpoint has almost tripled in price over the last 2 years. The small dmd is available, but pretty expensive.
So back to cp. IMO the game is kind of rare to find for sale, also is very niche for people who like porsche and racing. The games are from 91, so usually some pf paint wear and a broken ramp. The boards are getting older, could have damage. It is a dmd game though, so easily a $1k game. Oh and the red/pink ish areas could be faded. In good shape I can see this game being $1-1200 easily.
I got mine for a good price, but I've bought a nos pf, used ramp and after restoring it, I'll probably have doubled what I paid. But I love the theme and game. I'll be keeping this one
