I'm looking for a vintage road bike to take to school and I stumbled upon this 1970's Nishiki Single Speed on craigslist. I do not know much about bikes, but I had been riding my dad's old Fuji road bike until it was stolen out of our garage and know that I want another classic/vintage style bicycle.
What I'm wondering is what I should look for when I go to inspect the bike tomorrow. What are some things that I should definitely check out? Are there any deal breakers that I should be sure to look for? It would also be nice to know what you guys think this bike is worth so I can possibly negotiate a better price with the seller.
