The last 500 minis to roll of were cooper sport 500's your car was part of the previous batch of 2500 cars for uk plus 1000 for Europe, perhaps the 2nd last of that bunch, sadly, it cant be the second last but no less a rare and collectable car
If you like I can email you some numbers and try and find where abouts it falls I do have the list of final 500 chassis if not call in and see us at: http://www.coopersport500register.co.uk
There is an article there on the home page from the australian mini Expereince in pdf form if not the history of the 500's explains the knightsbridge and other LE's, which i wrote some time ago for the Register when I was looking after Rovers
