2007 Audi S4 Wagon Avant quattro 4dr Wagon AWD (4.2L 8cyl 6A)
I bought the S4 Avant (specifically not the sedan) because I have dogs and they go everywhere with me. I'm more than frustrated with the air circulation in this car. I live in Phoenix. Audi absolutely missed the boat when it comes to the comfort of anyone not sitting in the front. There are no air vents in the back (except on the floor) and while there are air vents in the back of the car, they're only for defrosting and work only when heat comes through them. I'm forced to drive my Volvo for four months out of the year because it's literally cruel to have my dogs baking in the back (even though the a/c is on high). Don't buy this car unless you plan to only have one passenger.
Honestly I like the styling and performance/handling.
Fix the air conditioning. This car is a sweatbox and anyone living in areas with temperatures over 90 degrees will regret owning it. For the millions of people in the US living in warmer climates, this should be a show-stopper. I dread every summer with my S4 Avant.
