Good luck with the sale. I just thought I would point out a couple of things. All Superchargers (and tintops) are imports as they were never sold in the UK. The mirrored alloys are standard on the supercharger I think so they are not rare on a supercharger. Did this car have folding electric mirrors originally and you have replaced them with standard UK mirrors which were electrically adjustable but did not fold electrically? Finally I believe superchargers had the same suspension as MK1b cars as standard, perhaps it has had after market springs fitted?
