Apparently my 71 LeSabre Custom 4 door hardtop is ultra rare. It has 54 louvers on the deck lid and louvers on the hood as well. They only did this for a little while at the very beginning of production, after that the used less deck lid louvers and no hood louvers at all. It is my understanding there were other changes as well and that there was a strike afterwards. So my car is pre strike and has louvers, the earliest one known to exist, it was built in August of 1970. Centurion said to me that my ride is so rare that I will never see another one. I wonder if even Bad Boattail in Europe has ever seen one. They have all the rare stuff there that I never see here. So now I can brag about my louvers, but probably almost as rare as the louvers are people who would care or be impressed. It will be my secret.
