found a Yenko Chevelle...please help

[APEX]

Hi, I just recently came across a LeMans Blue Yenko Chevelle in my area, but there is a slight problem...I don't know much of anything about Yenko Chevelles. I was wondering if you fellas could help me out by telling me various facts and information about the Yenko Chevelles. I have already been to www.copo.com to get the VIN's, car color information, and the total number of 1969 Yenko Chevelles built. I would appreciate any knowledge you are willing to share with me...such as how much this car is worth, how many are still around, etc. I plan at checking the car out later today, and will be back to let ya'll know if this car is the real deal and its condition.

Thanks,
Bryan
