I found a Warwick just like this one in 8 1/2 out of 10 condition. The serial number on the back of the headstock is J- 129651 - 06 . Here are some pics that I found on the internet that look just like the one I'm interested in. They're asking about $800 for it. Would this be a decent price? There are different Corvette Standard Series, and I'd hope someone would be able to pin it down. Thanks in advance.
