Re: Ford needs to use the Mustang Platform...
Well, Wings already addressed this, but I'd also point out that I responded to a different post than the one that you insist was your only (repeated, ad nauseum) point...and I addressed how you seem incapable of relating, in any reasonable way, to the reality that sedans are a dwindling market.
Every maker you've mentioned has seen that reality, yet you insist on "sending them the memos"...again, repeatedly.
If you're gonna do the digital equivalent of stomping your feet and babbling the same point over and over, even after it's addressed/countered (repeatedly)...I'm going to treat you like someone determined to behave stupidly.
It's called dealing with the presented reality, and you need some practice.
If GM can justify Buick, and if Honda can justify Acura, we can damned well have Mercury back.
