Meh. I sold one in better condition for less. £500 is average for a 3120, in fact until I messaged the seller about that guitar he couldn't sell it. It was on there for weeks at a higher price, then it went down to £530. I noticed it wasn't selling, so I sent a message suggesting he lower it to just under the £500 mark and it'll sell. Whaddyknow? It's gone. Mine sold at £490, but at the original asking price it didn't sell (£540). Seems people don't want to pay more than £500 for these. At £499 or less, they sell.
