Lotus Soapbox Racers Sold


News has reached us that the Lotus 119 Series soapbox racers have been sold.


News has reached us that the Lotus 119 Series soapbox racers have been sold.

The racers were built to race at the Goodwood Festival of Speed, and the fully enclosed 119C was never beaten. After the Goodwood FoS ended their soapbox racing in 2004, the 119 series were retired and used predominantly for display, although they were occasionally wheeled out to appear on TV.

It is understood that a deal has been done to sell all three of the racers to the Barber Vintage Motorsports Museum in Alabama, so it seems that these iconic British soapbox racers will never be seen in the UK or on a race track again.
