Hello All,
Sorry for the delay in answering this particular thread. Like other members -- my computer crashed on 1/28. Anyway, I have personally seen one 59 Imperial Crown Sedan with the 380 HP 300 - E engine. It was on a lot in Billings. The owner of the lot claimed that it was a one owner. By the time I returned it was already in the hands of a "demo" guy. I guess this qualifies as "the one that got away".
