Congrats on the bike trade.
Sorry to hear about the oil drip, though. I think many people put money into the classics because they just don't make them like that anymore. As cliche as that might sound. Same as an old Mustang or Camaro. It's done for love more than economical value.
I think, just based on your posts, if it were me with your bike, I'd simply park it where the drip isn't a mess (over a pan or some cardboard) and make sure it's topped off every day I ride.
The bike will hold it's value. There's a couple around here at about $2k -

Both have about the same miles as yours. I'm not sure what your other bike was worth, but I suspect you could sell the new one (if you wanted) for more. And being a classic, it will go up in value as time goes by, assuming it remains in good shape.
I'd just keep some oil with me and keep my ears open for someone who just
has to have this particular model.
