The 250 GTO body was developed by Bizzarrini and Scaglietti and perfected in a wind tunnel and on-track tests. This GTO (chassis 3505GT) was bought by the British Racing Partnership/UDT-Laystall team of Alfred and Stirling Moss. After running at Lemans, it was picked up at the Ferrari factory in the spring of 1962 by Innes Ireland and driven to England over 800 miles to compete in the Easter Meeting at Goodwood. Unfortunately it was at this meeting that Sir Stirling Moss had his career ending accident and the team switched Ireland to the lotus 19 original intended for Moss' use. Moss drove the 250 GTO during practice along with Ireland, but after the accident the car sat in the paddock for the rest of the weekend. The car placed first in a handful of races over the 1962 season including the Tourist Trophy at Goodwood and the BRSCC race at Brands Hatch. The UDT-Laystall team also participated in the 24 Hours of LeMans where they took 2nd in trials but failed to finish on race day.
This was the first right hand drive example built and the sixth produced in the series of GTOs. The GTO would remain competitive throughout the early to mid-1960s.
