I think you are mistaken what I believe versus what I believe general public opinion to be. The reliablity and build quality on MBs is no better than Cadillac - if as good. But the status of owning one of those is much higher for most people and that counts a lot.
the V doesn't even have to be as fast as the E55 but it has to be a lot closer than it was in this test where basically the MB walked away from it.
Hopefully GM is at work designing a 5.5 liter version of the Northstar with a bigger block to compete with BMW and MB
MB's status is declining, even in the eyes of the moderately knowledagble consumer. I don't even consider MB to be a staus car, I simply see them as very fast cars. I also don't purchase cars on their percieved status, I go by past expereinces (back 5 - 10 years, so I will try something again even if it was bad the first time. But that hurts Cadillac because current BMW and MB aged buyers grew up when GM and Caddy sucked for 20+ years), looks, materials, panel gaps and alignment / fit and finish.
If Chrysler offered a car that was good looking, great on the road, fast, and the build quality was excellent I'd consider the car, even if it was $77K (I would lease it because the depreciation right off the lot would be terrible due to the brands current perception. A few more cars like that would change things in a hurry.).

I thought it was your opinion, sorry for the misunderstanding.
