hi
what model s-type is it, what engine
theres were early production cars, there were a few s-type R's
the s-type R's that were prototypes had reg number BP51 KNW, BP51 KNT, BP51 KNR, BP51 KNS, BP51 KNU, BP51 KNV, BP51 KNW, BP51 KNX, these were proto types and still on the road.
also most prototypes had no emisions listed, so none were ulez exempt like a S-type R usually is.
just early production, none were destroyed.
cheers
Joe
