If it was as simple as "no more bikes, EVER" then I would probably tell them to do one, however if I needed to sell it on short term basis to fund something thats not a problem, unless if like StupidLuke I could not get a ride at home, id want something else to ride and would not get rid of my bike period. .
Thing is I dont do cars, I drive cheap reliable cars, so that saves me loads of money so they cant complain it costs too much.
