It will take a very long time to transform their dealer network into Lexus'. Most Lincoln dealers are under the same roof as Ford, and I don't see that changing anytime soon. The Baton Rouge dealership sells Lincolns under one roof, but the Ford and Lincoln showrooms are separate. Lincoln's dealer network will definitely be better than what it was before, but it will not be as good as Lexus'.
I doubt Lincoln will ever be a Tier 1 luxury brand. I think the safest and sound thing to with Lincoln is to keep positioning it as a value brand for Ford customers. It's possible they have no plans to actually play in the Tier 1 category, anyway. Their plan is perfect if that's the case. Like I said, if you want be a Tier 1 player, you must have a very unique, strategic plan put forward otherwise you're wasting a lot of money.
