History wise as Rallyretro pointed it out, it was not the most sucessful car Bertie had, presntation wise it was certainly the most striking and his last proper rally car. The car itself, was the very last 555 built by prodrive and the records do show this, but it was also built to WRC 98 spec, although what exactly this entailed prodrive were a bit vague at the time. The car with the most history attached is L555 FEL and I think the most sucessul of Berties cars.
But R555 FEL brought presentation, imaging and the rallying memorabilia to a whole new height in Ireland.
