Hi Tom,
Mine is a Burnished Brown L72/M22 from out of Michigan. It was purchased from one of the members of this site. Original engine is gone, but the rest of the car is there.
It's patiently waiting for my attention.( Once my 300 deluxe is finished!)
Through magazines and online, I count 8 L72 Biscaynes so far.
Zach, how's your car coming along? If it turns out half as nice as your 68, it'll be awesome!
