Well if you can’t do basic maintenance ( bearings,seals, chains, belts) standing on your head you better buy near new. Bearing, seals, chains can be bought at any most shops not a big deal. I’ve had older Argos and had issues with axles, shear pins, trans. Motors, carburetors etc., drive one day fix another. Buy fuel injected with newer admiral transmission with tracks and do your maintenance, you’ll love it. If you want a machine to rip around with buy a sled, side by side or quad.
