Craigslist Couch... Yea or Nay?

So, I was looking on Craigslist (probably while on the phone with my mom who was probably also looking on Craigslist) for vintage sofas. I troll Craigslist pretty regularly because it's like thrift store shopping from work. I never follow up on anything, aside from that one estate sale I saw advertised there... But I found two lovely vintage sofas that seemed like they were in great shape and had fairly reasonable prices. After e-mailing the sellers (just for kicks) and getting fast responses from both, I decided one was not in good shape (a vintage sectional that looked like it needed to be reupholstered=$$$$) and the other was lovely, but just too expensive.

Fast forward to now, the seller of the too expensive sofa just sent me an e-mail with three simple words: "Make an offer?" Whew. I'll talk to Justin about it, but I'm not sure what to do... This sofa is kind of far away, and we'd surely have to procure a bigger vehicle to get it home. BUT, the color seems like it would be fantastic in our living room, since it would bring out the reddish color of our Eames chairs. And it would mean we could move the current living room couch into the basement for our TV den that we will some day complete. It was listed for $500. What do I even offer??? Do I even want to offer??? I have been thinking that maybe we should just go new couch to avoid the ick factor, but this couch is tempting.
