It must have been a very long time ago when this person owned it, I would guess at least 25 years ago. I purchased in about 20010/2011 from Lothar Schuttler in Maryland (some will know him and his great collection) and he owned it for a good while. It was a place holder for me until I found a better RHD CSL, which I did a little while ago, a nice Taiga green.
Last year although it wasn't for sale, I had a dealer in the UK drive me nuts to sell him a car, although my plan with this was to put it in auction, I even spoke to Goodings about it and said I would be selling it when the Taiga car was ready - the UK dealer persuaded me to part with it early and it has now travelled back to its original home.
