I'd buy a manual CT5VBW in some reasonable color, black, grey, with the sports seats today for sticker + up to $5k.
However as I experienced before the terrible dealer base is going to be the main obstacle.
I spent a couple hour today calling a dozen or so local and regional dealers. Only guy that had a clue and is working on getting me an allocation was 1,000 miles away at Sewell Cadillac of Dallas. I did buy two V2's from him so I'm sure that helped.
Couple of my favorite responses-
"We haven't made a Blackwing for two years"
" haha you want one just like the 100 other dreamers that called me this week, you'd be better off trying to buy a ticket to the moon"
"Do you want a Landau top?"
Two of those statements actually happened, one not yet
