Do a BIG push and finish the car.. enjoy it and get the passion back..
I got burned out once.. sold the cars and became a "non car guy".. well not really since I got sad every time I saw a car show, event or nice musclecar drive by.. I would say "I used to have a car like that...".. the "used to" part sucked..
If you sell it you will regret quitting and giving up.. you will always have "what ifs" and everytime you see a nice 69 slide by you will be sad.
