I've never left a message here. I'm a little intimidated by folks who know so much more about their cars. I am in my 70's and my knees are not cooperating with the in/out, top up/top down. After a few weeks of physical therapy, not much help. The reason I am writing today is to ask for some "Solstice Advice". It is a 2008 base model. I've had it for 10 years. I have a second car that gets 50% better mileage but it ain't no fun to drive. If the sun is out in Coos Bay, Oregon, my Solstice top is down. When it rains here, the Solstice is in the garage. I haven't done anything special to it. It is an automatic and just went over 100,000 miles. Looks like the one at the top left of this page. And that brings me to the question - how do I establish a value? Any advertising advice would be welcome.
