Stunning and rare ONE-OWNER 2008 Audi A5 S-Line shown in Quartz Gray Metallic over black interior. NADA $34,075. KBB $34,005. , , With its potent powertrain, head-turning looks, comprehensive features, seating for four and creamy 6-speed automatic transmission, the A5 definitely raises the bar several notches. Fortified with Audi's legendary Quattro all-wheel-drive system, it's no surprise that the A5 is an exceptionally confident handler, but equal credit for that prowess is due to a new ultra-rigid platform design that features additional mass-reducing aluminum-intensive suspension components and a more pronounced engine setback that creates better overall balance. The A5's standard full-time Quattro system is designed to optimize the power balance to all four tires all of the time. While normally apportioning motive force in a 40/60 percent front-to-rear split via a Torsen locking center differential, it can vary those percentages between 65/35 and 15/85 as traction conditions warrant. , , In keeping with Audi's well-established tradition, the A5's cabin design reflects a masterful blend of contemporary style and impressive functionality. The impeccable melding of leather upholstery and wood and aluminum accents with an abundance of soft-touch surfaces and finger-friendly switchgear sets a welcoming tone for up to four people. To put it mildly, the A5 is an exceptionally well-appointed vehicle. Beyond leather and wood, its passenger compartment boasts a full array of power assists, tri-zone automatic climate control, multifunction steering wheel on a tilt and telescoping column, a driver information system, comprehensive Audi Multimedia Interface controller, 180-watt/10-speaker sound system with six-disc CD changer and MP3 capability, SIRIUS Satellite Radio, panoramic sunroof, rain-sensing wipers and cruise control.
