I once bought a BC Rich Ironbird from my local CC... It was up for about £100 odd, but I was concerned with the bow in the neck. The chap in the shop clearly had no idea about guitars, had a bit of a panic and offered it to me for £40. It turned out he had tuned it comically high - once tuned correctly the neck straightened right out!
Test the waters, see if the chap in your branch knows his stuff - if not, slyly suggest the bass is junk and see what discount you can get.
