Why it matters
The Mylord was Henri Chapron's open two-door conversion of the Citroën SM, often called the last great French luxury car. At more than twice the price of a standard SM it was made in tiny numbers; experts generally agree on five cars.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Chapron presented the Mylord cabriolet, his first transformation of the SM, at the 1971 Paris Motor Show. It cost 130,000 francs in 1973, more than twice a standard SM. The car kept the SM's Maserati-designed four-cam V6 by Giulio Alfieri, which with three Weber carburettors gave 170 bhp. Experts generally agree five were made, one of which may have been lost in a fire.
