Assembled over roughly fifteen years as part of a broader E-Type collection, the car features a cast-iron block straight-port engine tuned by Sigma, a full FIA-compliant roll cage and safety equipment, and an Old English White livery with blue stripes echoing the Briggs Cunningham racing Lightweights.
