I need some info for this car. Can you please compare it to the last car you had. I would really like to know how much you can carry in the cargo hold. Also I would like to know about the rear seat. (Audi A3 sportback in europe, just A3 in the US)

Just bought a '06 A3 3.2LQ S-line with convenience, winter, and premium package. Debated between an Allroad and an A4 avant. We bought it because we'll someday have little ones and wanted some storage space. I wanted something sporty, fairly good MPG, 4-doors, AWD, and navigation/bose. Rear seating is very comfy, especially with the open sky window. The trunk space is slightly equal to the A4 sedan, but cabin roomier by a few square inches.
Previously owned a 02 S4 avant, loved it, but traded it in on a '05 TT 3.2L quattro. The TT wasn't practical once I got married last year, but fun to drive.
Not very detailed but hope it helps!
