Buying Advice What's it worth?

[BadCobra]

I'm looking at a 2002 Scotts L2048 Lawn Tractor and I was wondering if anyone knew what this machine is worth? It needs an oil leak to be repaired but otherwise is in great shape and runs good. The oil leak is leaking onto the muffler and causes smoke. I'm not up on these so any and all suggestions will be appreciated. I'm purchasing this from someone I know that has bought a new tractor and didn't want to deal with repairing this one.
