Keep in mind you will be dropping about $3,500-$4,500 on a new loader.
If it low houred and clean it may be worth it you would have a nice tractor with a loader on it for 10k lees than a brand new one.
Not sure how important style is to youbut I believe the older 35's had a blocky hood while the newer models have a sloped hood. Sure won't affect how the tractor runs or performs.
Do you need a tractor that size or something larger?
Actually one does not have to open the hood to check the oil on the dk35se model, AND the toolbox is behind the seat on my dk35seand the flip open hood that makes it easier checking the oil Etc.
The older style DK had a tool box behind the seat, Which I really like. The SE model gives up that nice feature.
