well unless you have all the stock parts already, it's going to be a very long journey in going back to stock -even if you have the stock parts on hand ready to be swapped. the process of selling your mod parts and hoping to break even isnt going to happen, so take that into account as well.
there's also no guarantee on a buying time or a buyer in the first place, it's all subjective.
my recommendation: put it up on facebook, craigslist, washington post, ebaymotors, etc. some kid will probably swoop in and scoop it up.
