The more I think about it, the more I realize the best cars for me to replace my FiST with would be either the new one, or the Hyundai i20 N, neither of which we can have here in the US. I love how light our car is, and anything else that I think about replacing it with that is available here is significantly heavier.
This confirms my hope to not have to replace my car, I plan to keep it forever.
