The eye-catching 2020 Alfa Romeo 4C Spider, manufactured in its final production month of December that year, stands out with only 6,000 miles on its odometer. This sleek convertible sports car is powered by a turbocharged 1.7-liter inline-four engine mated to a six-speed dual-clutch automatic transmission. Its striking white exterior complements the interior's luxurious red leather upholstery.
