Theย McLaren F1ย is, in and of itself, a legendary supercar. Then McLaren took them racing with specialย GTR versions. Out of those GTR versions, in only 1997, ten were built as the FIA GT World Championship spec โLongtailโ versions. Chassis number 19R was the first of the GTR Longtailโs made, and it was also the first to be converted to road-ready specification once the GTRโs stopped racing.
