reginos:

Audi designs (saloons and hatchbacks and their derivatives) are pretty and neat but they don't differentiate much between models and model years and consequently after a while they lose their freshness.

Also for me they don't generate any emotion. Like a pretty woman who doesn't attract.

Fair enough on the emotion side for you in particular,
 

But if a car looks good, why should it ever change (lookswise) - take my 928 for example. Never changed the interior over the 18 year run, why change perfection, one change to the exterior (1987) and sales fell.
