Why buy an S4?
Stealthy looks, exclusivity, all season drivability. Audi expects to build about 2,100 a year - chances are you won't see one in the parking lot. And, true, four season capability means you don't have to park it for the winter and add another vehicle to the family fleet.

What's the downside?
What's stealthy to some is subdued to another, in terms of styling. And the air deflector should be a standard feature at this level, not an option.

How about other options?
An audio upgrade (Bose sound and Sirius satellite radio) costs $1,000. The Premium Package adds the wind screen, memory features and auto dimmers for $875. $450 for heated seats will seem like money well spent unless you like the feel of cold leather on a frosty winter morning.
