While I like Kubota's and their diesel engines your Gator is ten years old and worth about $3900 on trade for an RTV 900. If you are contemplating something specific that it will do that the Gator doesn't I suppose it is worth getting but if it is just to trade up in would not make sense to me. 1080 hours in ten years is nothing and you know what kind of condition it is in. I would keep it given my uses for a side by side.
