Re: IBANEZ RG550 2002 which color is this?
You should not keep it unless you're going to pay for it, the guy's a pensioner and probably needs the cash.
It is NOT an RG550 and is not worth much since it has TRS101 trem and V6 pickups although it is in very nice condition.
Since the RG250B was only available 1995-96 there is some ambiguity here and I suspect it's a parts bin special for the Japanese domestic market only, possibly a spot model.
Personally I wouldn't pay more than 150 Euros for it but you should make your own mind up if you like it.
