I'd separate out the CSL City Pack cars and the early really lightweight CSL's.
Yes, agreed. Carb'ed early CSL should be #2 or even #1 on the list, especially in in Inka, Taiga, etc. Make it an Alpina early CSL and that vaults to number one on my list, if you can be certain it is real. Like the one that Ben Miller had at Legends of the Autobahn this summer.
Personally, I think the BAT kit is ugly, despite its historical significance. It might confer the most value, but the wing ruins the lines of the car. The race cars looked cool, but the wing just looks silly on the street, the same way a triple decker whale tail on a 911 looks.
