If it’s actually in good shape, it’s a steal. Can you get pictures of the serial numbers from them so you can look it up?
Hopefully it’s a real posting and not someone scamming-Craigslist is horrible about that.
A proof of life photo helps. Yknow, the guy holding today’s paper with the bass. If it’s real and they want to sell it, a picture shouldn’t be an issue.
Good luck my friend. And please be careful, Craigslist is fully scary.
I would be very skeptical of any Gibson that looked like a killer deal. Lots of (sometimes better!) knockoffs, and Gibson is famously way more variable for quality than other big name manufacturers.
I would basically not buy a Gibson I had not checked out in person extensively myself.
