i would keep it. toss it in a closet and close the door for a while, and come back to it later. you won't get anywhere close to what you put into it if you part it out, and it may be a fun 'project' car someday when you're more objective about it.
i've regretting selling a handful of cars... including a $2500 SuperMaxx and a $2000+ crawler. seemed like a good idea at the time, but i should've kept them.
