DL41L1D178414. Looks really nice. GY8 with GT8 dark tan interior -- cool color combo.
This is likely the first 1971 Polara that I have seen with L35 cornering lights but without L31 fender-top signal repeaters. P25 power front bench, too. Love it.
I found another video of the same GY8 Polara Custom, uploaded by Maple Motors in KY a few days before the other one posted by @King Hooter -- @polara71
