How secure is your workshop area?
I'd be tempted to say your pushing it outside and it's staying there for good,leave it a few days and take the goodies off and scrap it,not your responsibility then.
Trying to sell it would be a nightmare,but selling bits on eBay would be easy,even take the goodies and partially burn it,claim kids did it then scrap it,believe me the filth aren't interested,I had sone little scroat try and nick my impreza from outside my unit,had plenty of witnesses etc and they never even came too look at it,gave me a crime number and spent at least an hour at the computer to tell me yes it was a silver scooby!!
Put the phone down in the end and fixed it for about £50,found the alarm in the yard and soldered it back in,in fact I gained as the little cunt stole a battery out of someone else's car to try and start it as the one in it was flat!!!
