1966 Buick Skylark Gran Sport – 401ci Nailhead | Silver Mist & Regal Black | Factory Style, Muscle Car Soul
Here’s a rare opportunity to own a true 1966 Buick Skylark GS, finished in a striking Silver Mist body with a contrasting Regal Black roof, factory-correct 401ci “Nailhead” V8 under the hood, and just the right mix of originality and muscle-era flair.
