The 2006 Audi A3 S-Line is a wagon with sex appeal. With no competition in the field from other luxury contenders, the V6 AWD wagon fills the niche of luxury and practicality plus performance. The A3 S-Line is a bit shorter than other wagons but the passengers do not suffer (just the cargo space). There is still ample leg room, a high seating position, leather seats, firm cushions, and adjustable head restraints. The S-Line has the Bose sound system as standard, but you will still be paying for other options like satellite radio, navigation, and Open Sky roofs. However, the S-Line starts 10 grand higher than the regular A3 2.0, at a bit below $35,000.
