You can see if Amazon still has one left but no, they only made them for like a year and quit making them back before this topic was started and they were no longer high end and bargain priced because they were just to heavy for pedal power and Cadillac pulled their name rights.
My shopmate and I each bought 3 before they were gone. All were motorized but one he still had in the box which is now mine to motorize with an electric shifter.
Naw De Naw Naw hehehe ;-}
We just played our cards right is all, and found the right source and took all he had (bikes4falmiles.com?) as I wasn't a stranger to NuVinci and jumped at the chance to get a killer bike for less than the back wheel cost.
If you want a shifting Caddy with an electric it will be for sale after I have some 'extensive test riding' miles on it for ~$1500 and I can ship it easy (no gas).
That is actually just over what the electric kit goes for (36V 960W) and it's doubtful you could even find a boxed new Caddy bike but check your local Craigs, you never know, just search in Bikes for 'Caddy', 'Cadillac', and 'Fleetwood', you may get lucky.
Just for reference since there are no posted pics this is a Jackshafted caddy with a 66cc on it.
This electric will be much more sleek ;-}
