$3,900 · VW rabbit convertible

1981 VW rabbit convertible, I have owned this car for the past 5 years, driven only in the summer months. Parked under a carport in the winter months. Over the past 4 years ive replaced : Brakes Clutch Fuse box Engine mount Tires Shifter bushings Fuel filter Etc... It's a 5 spd manual, the top was almost new when I bought it. The top is still in great condition as it was covered every winter. The bad: It needs a battery asap It has a slight running issue that I noticed November of last year before parking it for the winter. It still drive fine, just occasionally sputtered. Other than that regular maintenance has been done and it's one the cleanest ones around town. 3,900 or best offer
