I just think of a car like the Mazda6. It got rave reviews from everywhere and is a great car, but it hasn't sold as well as expected. Mazda is a smaller brand, not one of the big mainstream ones. I think that there is some unknown factor and also a momentum factor. If people are not flocking to Lincoln now, I can't see them doing that just because of the MKC. If the MKC doesn't sell as well as you think it should, it won't be the MKC's fault, it is just a matter of the whims of the masses.
I see your point. But look at the 6's competition ... Camry, Accord, Fusion, Altima, Sonata, Optima, Legacy, Passat, Malibu, 200 and any others I may have missed. There really isn't a bad car in the lot, and most of them are priced very aggressively with incentives, rebates and/or special financing. The 6 has been well received among enthusiasts, but not so much among the masses. And unlike nearly every other car in the class, there is no engine upgrade available; plus there's no AWD or hybrid version available. There is simply not enough to separate it from the other offerings. Simply put, the 6 is marketed to a small segment of a large market.
In the near luxury-to-luxury crossover segment, we're dealing with far fewer direct competitors, and half of them suffer from reliability and/or dealer customer service issues. Those shopping for value and/or reliability may avoid the Europeans. The RDX is probably the closest direct competitor on price, at least until the NX arrives, and they sold about 4,600 in March. If you've looked at the RDX you know they are missing a LOT of luxury features. The MKC simply blows it out of the water on features and technology. The SRX continues to sell well despite it's age. In fact, the SRX is Caddy's best selling model. The Q5 and RX are the top selling models for their respective brands as well. If Lincoln follows suit with the MKC, it will have to sell at least 40k/year just to outsell the MKZ.
Or maybe I'm full of sh!t. I guess we'll find out soon enough.
