I have an 09 wrx that sits more than I drive it, but I have recently done some upgrades that make it the go to car for any kind of serious rapid transit. Easily the most capable car I have ever owned and while I dont drive it much I cant realistically consider letting it go. When I do drive it, the enjoyment makes it all worthwhile. I understand the mental gymnastics you are going through though....making payments on a toy is something that gives one pause and makes you consider if it is worth it. Ultimately you must decide. I would keep it if I could, but that is just me.
