I've had difficulty finding their sales figures online.
From my personal experience with both, they are fine looking cars that drive well (according to reviews). However, their interiors are so putrid in design, material quality, and fit-and-finish it's pretty inexcusable. Honestly, I feel the E90 and E60 BMWs (decade old designs) had nicer interiors than these cars. Heck even a new Honda Accord has better fit-and-finish. It would boggle my mind if people were actually buying these in even respectable numbers given all the great competition out there.
If anybody wants to see what I'm talking about, look no further....
