 I will never by another Audi.  This 
vehicle has had several major 
mechanical issues, and the manufacturer 
has refused to cover them since it is 
out of warranty.  A vehicle in this 
class with relatively low mileage 
should not have these issues (and our 
Infiniti doesn't).  It is the most 
unreliable vehicle I've ever 
purchased.  I know several other owners 
who had similar experiences.
