Joe,
I'd ask for the serial number so you can post it here in the club to find out what kinds of woods, features, etc. it has. Does it come with a case or gig bag? I'd also ask for more detailed pics if you can get them.
As this is a garden variety Essence, e.g., one without extra features, custom touches, etc. I'd say this is probably closer to $1500 in terms of price. If it doesn't have a case, or only a gig bag, that might also knock the price down a bit. Ultimately, this bass will only be worth what you're willing to pay, so I'd ask these and other questions first before taking the plunge. You might also want to see if you can play it first if you are geographically close enough to it.
Hope this helps,
Alan
