That is an old 1980s clunker worth about $30. Fine as a "grocery getter"
Sellers on Craigslist seem to think their old clunkers are valuable just because they are old. 99% of them are wrong.
How tall are you ?
Not many road bikes in your area. If you end up with a mtn bike, you can put on narrower slick tires and put 80+ psi in them and it will roll pretty well.
This is nice if you are 6 feet tall
