Sorry, I'm not familiar with the model. From "HG" I can only guess it's a Grand Auditorium size in the Heritage series.
I wonder if you've got the model number right. Washburn does mostly indicate value by the digits, but unless the one you're looking at shows a lot of detail (binding, inlays) or quality woods, I suspect it's more a "7.5" than a "75" (like the D100, which is a D10).
You say nothing about the price. It's difficult to set a value for a short-lived model, especially one that's fairly recent.
If you need an acoustic guitar, & you like it, & it sounds good & plays good, then you probably ought to consider buying it. Waving cash might be a good way to bargain the price down a little, especially if it's been hanging there for months with no interest.
Twenty years ago, I paid $250 for my plywood Alvarez. Still my main acoustic. So I'd have to say that if the HG is in the $250 range, then buy it. If it's in the $500 range, or if you're not excited about playing it, then you could walk away.
If your main intent is to sell it for a profit, then enjoy the gamble.
