When do you give up? In terms of true practicality, we all should have quit before we started. Before you give up, go to some big car/truck shows and see if some fine examples of what you like doesn't light a fire in you. If not, give it up and sell it. There are addicts like myself lurking in the shadows, ready to prey upon an abandoned, unfinished project. Just don't expect to recoup even half of what you spent on just the parts. I am purposefully being harsh to you so that you will think it through and not regret whatever decision that you end up making.
