Well, here's my input: start viewing your vehicle differently. By that I mean, drive it a lot, and put the top down whenever you can. I understand you've put a lot into it, but that's probably been fun in and of itself. It could be a show car, but I think you could gain your investment back in smiles and letting it get a little scratched up. Perhaps even raise it in the winter and put snow tires on it. You'll never get that money back, so you can either sell and lose, preserve and snore, or pretend it's brand new and you are going to drive it til the wheels fall off and have a blast. Surely this isn't too dangerous for man such as yourself.
Whatever you decide, good luck and best wishes!
edit: didn't realize it was parked away from your house. Tough call. Move closer to your car? haha
