Their first car, the Xylon, which had gullwing doors and a windscreen in four panels, was nicknamed the "ugly duckling".  A total of nine, aimed at 750 Motor Club events, were built in 1959 and 1960. For production the body was made less radical but initially retained the gullwing doors. It was powered by a choice of [[Ford of Britain|Ford]] engines varying from 997 to 1498 cc and had [[Standard Motor Company|Standard]] 10 and [[Triumph Herald]] steering and suspension components. Thirty-nine were made up to 1963.

In 1961, brothers Dennis Adams and [[Peter Adams (designer)|Peter Adams]] started working with Marcos and introduced several changes to the original design.  The Marcos Luton gullwing and the spyder were introduced in November 1961.  This design was again reworked, becoming the Marcos fastback GT, which was displayed at the London Racing Car Show in 1963. The chassis was fabricated from laminated 3&nbsp;mm thick sheets of marine plywood, giving the cars strong monocoques and low weights (the GT was internationally homologated with 475&nbsp;kg), so they performed well in sportscar competition. Most early Marcos models competed in national and international events.
