1969 Z10 Camaro

[69SSRSL89]

I've got a good friend who is in the process of getting his 1969 Z10 ready to sell. He asked me what it's estimated current value was and I'm not sure so I thought I'd check here to see if anyone could help him out. It's a very nice car and restored very accurately. It's a numbers matching 350 M21 4 speed car. It's got black standard interior with a fold down rear seat. It's got console with gauges and an endura bumper. I think it might have a couple other options, but these I know for sure. The engine bay is detailed out to factory specs and equipped with the A.I.R. system and has a factory style exhaust system on it. Any help you can provide would be greatly appreciated. Here are a couple pictures that might help give a fair estimated valve on the Z10. Thanks again for your help.
