That's a good question. On the Hybrid, this might be a concern to some people. Would be interesting to know what the impact will be on the V6 - I guess far less.
The Pano-roof is an amazing feature on this car but after all, it is also quite expensive and therefore, it has to be a perfect fit to become a success. The "package" has to be right.
Although it's somewhat OT, but I would really like to know if the power rear sunshade could be retro-fitted once you order the car with the pano-roof since you can't order both features at once. I hope all MKZ's will be pre-wired for it. I guess many readers might be bored by now by me pointing out this ordering-conflict - but I think it might be quite important.
The availability of the sunshade may only be a minor issue for some potential buyers, but some might consider saving some $$ and going for the sunshade and regular moonroof instead. I realy hope that Lincoln finds a way to offer both at some point in time because if they really want customers to opt for this pano-roof, they certainly shouldn't deliver any arguments to them to NOT opt for it by excluding other features in return. In the luxury market, "either..or" doesn't sell too well.
I understand that the lower MPG-rating probably is a result of simple physics so I won't blame Lincoln for it - but it's an additional factor that might lower the number of ordered pano-roofs. Assuming the development of this roof was everything but cheap, I guess they want to sell as many as possible. That's why they shouldn't exclude any other options in return and and prevent it from becoming less desirable.
My 2 cents..
