Yes. Sell it. It's free money, except for all the taxes that have to come out of it (that's taking money away from you for a free gift). In two years cars will get better gas mileage, although I think Civics get good mileage anyway. Probably even better in two years though.
Or pack it away for two years if you can. If it's moved around you have to pay insurance and the license plate and the maintaince, etc.
