The Jaguar XKE Series I, crafted from 1961 to 1968, is a legend wrapped in a sleek, stylish body that even Enzo Ferrari dubbed “the most beautiful automobile ever.” With a 3.8-liter engine and a later upgrade to 4.2 liters, it was the sports car that could whisk you from zero to “I’m late for tea” in about 7 seconds. Known for its quirks like a hood latch that required a special tool, it’s no wonder collectors clamored to keep these beauties in mint condition.
