The only issue with a 2 year old bike with only 500kms on it is warranty. If a bike is going to have any problems, it usually happens in those first few thousand kilometers. That wouldn't stop me from purchasing the ride though since I'm a mechance. Not sure if that is an issue with you.
Personally I'd take the chance and go for it. The Xs are vary rare with only 500 made.
Oh, welcome from Canada.
