My plan of action to bring the car back:
Find out why it is only getting 22 MPG's and not closer to 30.
Remove the rust and get it painted. (Matte red with a matte back stripe or matte black trunk and hood?)
New top.
New dash and new console.
Then the fun stuff:
Older style bumpers
Speakers in the footwell (Holes and wires are already there)
Better suspension
I have replaced the back seat with a speaker deck with a pair of 6x9's and I am looking to add a luggage rack.
I am part of DC Fiats, but I have only gone to one tech day. I swear I will get to more stuff!
Looking at the bill for the rust repair and top alone, I might end up buying a rust-free Spider, then use the one I have now for a parts car, who knows.
