I'm having a tough time deciding if I should spring for a used 2006 A3 or a used 2007 S-line. What exactly are the differences for the 2.0L versions? I can't seem to find anything on it.

 

Not much difference really. Do a search on this forum and you'll find a couple threads discussing this subject. Depending on mileage, the 2006 should still have the full maintenance program. The 2006 might have a weaker A/C compressor and DV. A couple package changes, badges, and a minor front grill change, but nothing major.

Cheers!
