2013 Elantra needs to be parked for 2 years. Park or sell?

Friend got a license suspension for 2 years. 2013 Elantra 40k miles, $11K left on loan. Should it go on blocks for the duration or should he just sell it while it's still worth something? Also, if he keeps it parked outside, how hard would the two year inactivity be on the car? Thanks via /r/cars http://ift.tt/2ua4VCb
