HELP!!! I don't want to get scammed!

So I'm a roadie and looking for a mountain bike to just go around campus on.

I have found a almost new DiamondBack (dont know what) on craigslist for $75. is it worth me driving almost an hour to look at it? should i just remain patient?

please help!

you should post the link to the bikes you are interested so that people can give you some advise. it's very hard to buy used bikes, especially on craigslist since most people don't even know what they are selling.
