Losing interest in the hobby
Stop going to the shows. Just get in the car and drive! Hang out with friends/fellow car people and enjoy it. Cruise nights and such are fine, but just don't enter. I know the negative comments hurt. None of my cars were ever "show worthy" in my books, so I just went to enjoy other people's rides. I haven't owned an old Mopar in over 3 years now. I took Dad's Dart to work last week, and the feeling was just indescribable! Take a break, if need be, find somewhere closer to home to store it, if possible, and throw the cover on it. It will be waiting for you when you're ready.
