So my question is response is...what sedans don't have this feature and why? As we know pretty much all estates and hatches have this feature to increase the little cargo space they have (hatches) and increased utility (estates, SUVs). But the presence of this option is highly variable in saloons across the board.
I can think of two situations where they are consistently NOT found:
1. really cheap low end, base model compact sedans - reason? I'm guessing its cost issue
2. really expensive high end luxury sedans i.e. S Class, A8, XJ, 7 series, etc.... reason? Obviously its not a cost or weight savings issue. Could it be that feature is seen as too 'bourgeouis' for the type of ppl who own and drive these kind of cars? i.e. manual labour and moving stuff is beneath them, they're not the type to buy cheap flat pack furniture, the trunks are spacious enough for most transport needs, etc...
Discuss away...
