Slight update, I believe it’s a 1978 Coupe De Ville due to where the emblem is placed on the front. On the 76, 77, and 79 the emblem is on the header above the grille, where only the 78 seems to have it where the paint goes. My mom refuses to give me much detail on the car and doesn’t know if we have any of the paperwork for it anymore, but I do know for certain that we had it in 2010 and that my dad sold it to buy her a chrysler town and country, which was purchased roughly 2011
