I'm looking to buy a new S4 with about 178,000 miles on it it's a 2002 Quattro it's only $5,500 but Im wondering if it's worth buying and about how much longer it would last me

The 2002 Audi S4 is unchanged from the previous year. This sports performer is cleverly hidden beneath the classic, sophisticated, unpretentious trappings of an Audi four-door sedan or Avant wagon. Superficially, it looks like a practical, yet luxurious family car. The S4 Avant offers lots of cargo capacity, with fold-down rear seats A leather and wood interior screams elegance and style.
But don't be fooled. By day a mild-mannered commuter, at night and on weekends the S4 turns into The Flash. Equipped with a sports-tuned lightweight suspension, strong shocks and brakes, the 2002 S4 features a 2.7-liter biturbo, 250-hp V6 engine. Though you can get it with a 5-speed Tiptronic auto/manual transmission, most drivers recommend the standard 6-speed manual for maximum low-end torque performance and driving fun. In terms of safety, ABS brakes, electronic stability, dual front and side curtain airbags, and special sports seats with side bolsters keep you secure. The 2002 S4 is really an all-season/all climates sports sedan/wagon, because it features quattro all-wheel drive, which distributes power to the wheels that need it most. The result is a solid, stable, confident ride that rivals most SUVs in terms of performance.
Not surprisingly, drivers call the S4 a rocket. They love its amazing power and low-end torque. That and the twin turbos give a more responsive powertrain with very little turbo lag. Expert steering and handling are also mentioned. The luxurious interior and comfortable leather seats don't disappoint. Some drivers dislike the placement of the cruise control on the steering wheel and the useless location of the cupholders. They would like memory seats to be offered and don't like the "notchy" shifter which can be unresponsive. Drivers also suggest replacing the 17-inch tires with 18-inch ones. The usual complaint about unhelpful Audi dealers is mentioend with the S4 as well.
