I quite like that front end on the 3dr.
Very unusual as all the mk 2 3dr sierras were left hand drive, and they also have the saff fuel filler with the big flap, that shell has a mk1 filler.
My guess is someone has reshelled a 4x4 saff cos into a mk1 3dr shell and fitted the front end from the donor and transfered the ID from the saff into the 3dr shell and then made up a story about Tickford being involved.
