Yes, the B-body is dead, has been dead, get over it. The B-body will likely never return and if any BOF car is ever built again, it'll be on a different platform. Also, those are nameplates, man, not chassies. There's a difference. The Camaro is returning as a RWD, V8 musclecar, but not on the F-body. Find me one person who gives a shit.
The basis of your argument is this body-on-frame kitsch. Where are you going to build this wonder barge? No BOF car lines exist and I doubt one could translate a GMT chassies into a slick Cadillac.
Look at DeVille/DTS sales stats. Old people and yacht-lovers crave them and have padded the Cadillac purse for a decade without the Fleetwood. DeVille gave the Fleetwood buyer most of what they were used to and more gadgets while sacrificing RWD - which some care about - and frame construction - which nobody who bought them except livery companies care about.
Also, if this is such a lucrative market, don't you think Cadillac should've pursued it more back in the early-90s when it had a Fleetwood? Show me stats to prove me wrong, but I have a feeling Lincoln handily outsold Cadillac in the low-profit fleet market back in the '90s.
This makes no sense in regards to this argument. And its a fact that fleet sales account for far lower-profit margins than retail sales because fleet buyers typically do two things:
1) Buy the cheapest, strippest trim available.
2) Want a massive discount on it.
Show me the profit compared to a retail car loaded with options.
You're also talking two different fleets. You propose this BOF car because limo companies want to chop them up.
Yet, you retort still?
Look, plain and simple: Your desire requires GM to have a plant to manufacture this car and honestly, GM has a lot more problems right now than this. If only they had the luxury of worrying about a low profit, lower-volume segment that'll costs lots of money to get back into.
Tell you what. You shut up and support the FWD unibody DOHC shitboxes like Epsilon II and the Lambada crossovers that help General Motors compete and make some money again and when the glory days of deep pockets and big bucks return, I'll be there to personally lay the keel for your boat, 'kay?
