here's the 80's citroen XM
pretty low Cd 0.28 or 0.29 i believe...not bad for such a boxy look... but i mainly like the wheels! these are one of my all time favorite rims
i think carmakers urgently have to reintroduce full hubcaps... they'd look awsome on the curent size of wheels...certainly would give even existing models a new more spacey look
