I'm pretty sure I'm going to sell my 1989 Sundance. Any thoughts on an asking price? It's got the 2.5L Gas, Sunroof, pretty good condition for a Wisconsin car. A little rust along the bottom of the doors. Get's about 35mpg on the high-way and about 25 around town. It has been my daily driver for the past 3 years. 109k miles. Any thoughts?
