1978 Honda Civic

I bought this honda in non-running condition, nd worked to get it up and running again. It's got an almost completely rebuilt engine. But as an college student I can't put in the upkeep necessary for a classic car. Hate to see it go. Right now I have a new car so I don't drive it everyday but before I got it it was my daily driver. It doesn't run as well as it used to and could use some work-its an old car. I've put over $2000 in it.
