As long time Warwick enthousiasts who have been moving around in the used market for years, we have a good pov on the fairness of prices. If someone wants to sell his used bass for a price that is not even close to being in line with what most others are selling for this is not called freedom but stupidity.
When multiple would-have-been-buyers point out the asking price is about double of what would be fair, and nobody ever got close to wanting to pay the asking price the seller should start to wonder whether or not he is doing the right thing and whether or not he has payed way way way too much for that instrument himself in the past.
There's a SS2 5str on ebay.de for 4500 euro, it has been on there for three years now and probably will be on there for another 3 or more... Just saying...
