Welcome to EKN Dustyn. If you are referring to a Margay K3 kart, I’m sure you can find out what year it is. Find more about them at http://www.margay.com/
It’s a great chassis to start off in the sport, along with the Briggs 206 engine.
If it’s a good deal, go for it and you can always upgrade the chassis when you become more familiar with the kart and racing.
