Would you like to finance that for me? I'm not spending that much on any project, then try to sell it.
Just depends on your mission, or your target demographic for selling it.
If you're just semi local area straight VFR ops, you don't even need a GPS, leave it as is.

For what you're in the plane for I think a semi basic Skyview install would be great, she would be a instrument ship and something I wouldn't have a issue taking from coast to coast, plus a buyer will pay a more for a thought out and capabilbe ship, just dump a basic Skyview in, spruce up the cosmetics, maybe add a starter and you got a real plane.
With a few improvements that would be a great little commuter, one of my buddies just got a experimental like that for a work commuter.
As she sits I wouldn't pay too much for a very home built looking plane, you still got a hell of a deal, but if you're going to flip it, cosmetic stuff and a redo of that panel and starter would be in order IMO. Another thought is to advertise her as a built to order and have the customer pay for the avionics etc directly.
Ether way, sweet deal Tom, look forward to hearing how she shakes down once you pick her up
