2004 POLARIS Sportsman 600

Hey guys, I just bought a 2004 Polaris Sportsman 600 today. It has 150 hrs and 1000 miles. I paid $2400 for it. First off, did I get a decent deal? Secondly, what are some suggestions about maintenance to make sure it runs strong for are long time? It has no leaks, good brakes, all cv boots look good, fires right up every time and runs strong. AWD works great and shifts through all gears easily. It does need to be choked for about two minutes till it warms up then it’s good to go.
