Y539 OBL is VIN Number 105, built on the first day of full production and being one of only 12 built that day according to records. It was bought from Laindon in Essex and although I am the 5th owner on the log book ,two of those are dealers. The car features the grooved seats which apparently didn't make it to full production...possibly apart from this car maybe unless they were added later but the rarity of the seats would suggest this is probably not the case.
