The word I meant was proprietary, not propriety. What I meant was maybe reliability statistics are not publicly available because they are 'trade secrets'. There has been some discussion on this forum about powershift reliability, see user Mondaveo on that. Problem is if they do fail they are very expensive to fix compared to most. Servicing is also expensive, if you don't DIY.
On the other hand second hand values are low on account of the percieved powershift reliability issue, which only badly affected the dry clutch type on Focus.

I do mostly highway driving, so fewer gear changes. Probably a big factor.
The Ford roof racks on my station wagon are removeable cross bars 1200mm max apart.
Where the wagons really excel is in interior space.
