I have one of these. Surprised to see an article about one, (and Mark IV's in general) on Hagerty, as mine's insured with you. I bought it in 2018 for my 21st birthday. It's got over 100K miles on it, but still in really nice conditon. It has the power moonroof too, as well as some other expensive options, including AM/FM 8-track, power vent windows, cruise control, illuminated visor mirrors, forged aluminum wheels, etc. I ordered an Elite Marti Report for it, and it shows a total of only 714 Desert Sand Luxury groups were built. They weren't introduced until March '76, and mine was built late, in June '76. It is 1 of 12 built exactly like mine, with all the same options. Oh, the report also has a reproduction window sticker in it that shows the total cost was a little over 14 grand, just like the article mentioned. Really fun car to cruise in. Just floats down the road, like you're on a cloud.
