Agri, I'm going to go out on a limb with some advice here ... I haven't seen the boats you're looking at, but I'd approach it like this: both the Vega and Vancouver are small boats and should have low refit and maintenance costs. The big costs are likely going to be (a) engine replacement, (b) complete re-rigging and (c) a new suit of sails. If the Vancouver has a new engine then I'd look carefully at the rig
and sails. If they're in good shape, I'd go for the Vancouver providing the hull and decks are solid. Most of the systems in a boat that size are going to be both simple and inexpensive to fix and replace. You'll likely have foot pumps
for water, no fridge (just an icebox), no fancy systems. A simple boat is easy to maintain and you'll find that you can do the work yourself without it becoming onerous. You're getting a lot of boat with the Vancouver, especially if your plans include sailing off into the sunset.
