THE BREAKDOWN RM Sotheby’s lists the 1958 Ferrari 250 GT Cabriolet Series I with a $4–5 million presale estimate. The most talked-about Ferrari at Monterey Car Week this year is not a modern hypercar.

That number raises two questions for collectors: what sets this 250 GT Cabriolet apart, and is $5 million wild money or in line with today’s Ferrari market.
