Excellent-condition 2020 Buick Encore GX Preferred AWD with a well-documented ownership and maintenance history. The vehicle comes with a full CARFAX report showing 28 service history records, with the majority of its maintenance performed through Lester Glenn Auto Group, where the vehicle was originally sold and serviced. CARFAX classifies it as a “Homegrown” Lester Glenn vehicle, meaning at least 75% of its reported service was performed there.

The current owner purchased the vehicle in early 2024 with approximately 119,574 miles for $16,999, and the original purchase receipt is available. The vehicle now has approximately 121,800 miles, meaning it has been driven only about 2,226 miles since purchase. CARFAX confirms the second owner has used the vehicle very lightly, estimating only 849 miles per year.

CARFAX shows no accidents or damage reported, no structural damage, no airbag deployment, and no odometer issues.

The service history is unusually extensive. Lester Glenn records include regular oil changes and tire rotations, brake service, brake-fluid service, differential service, air-filter replacement, alignment work, and other maintenance. The vehicle was also serviced immediately before its 2024 sale, including brake inspection, resurfaced rotors, rear brake pads, wiper blades, oil service, tire rotation, and detailing.

The battery was replaced in January 2024, and the most recent CARFAX-recorded service was an oil and filter change and maintenance inspection on June 6, 2026 at 121,645 miles.

Best selling point: only 2,226 miles added since it was purchased at 119,574 miles, combined with 28 documented service records and a clean CARFAX. 

Vehicle Overview Description

The 2003 Audi S6 Avant is a rare combination of V8 performance, Quattro all-wheel-drive capability, luxury, and genuine wagon practicality. Built during one of Audi’s most celebrated eras, the C5-generation S6 Avant delivers the understated styling of a European sport wagon with the performance of Audi’s naturally aspirated 4.2-liter V8.

Under the hood is a 40-valve 4.2L V8 producing 340 horsepower and 310 lb-ft of torque, paired with a 5-speed Tiptronic automatic transmission and Audi’s legendary Quattro permanent all-wheel-drive system.

The result is a performance wagon capable of delivering strong V8 acceleration while remaining comfortable and practical enough for everyday driving.

Performance & Quattro AWD

The S6 was designed as much more than an appearance package. Audi equipped the Avant with a sport-tuned suspension, larger brakes, wider wheels and tires, and Quattro AWD to create a wagon capable of handling both performance driving and poor-weather conditions.

The naturally aspirated V8 provides immediate throttle response and a distinctive exhaust note without relying on turbocharging. With approximately 340 horsepower, the S6 offered serious performance for a luxury wagon of its era.

Classic Audi Sport Interior

Inside, the S6 combines Audi’s traditional high-quality materials with a driver-focused performance layout. The cabin offers comfortable seating for five while retaining the refinement expected from Audi’s flagship performance models.

Unlike a traditional sports sedan, the Avant body provides substantial cargo capacity behind the rear seats, with even more room available when the rear seats are folded.

A True Audi Enthusiast Wagon

What makes the C5 S6 Avant particularly special today is the combination of features that has largely disappeared from modern vehicles:

• Naturally aspirated 4.2L V8
• 340 horsepower
• Quattro permanent AWD
• 5-speed Tiptronic automatic
• S6 sport suspension and braking system
• Wide-body performance styling
• Five-passenger seating
• Large Avant cargo area
• European sport-wagon character

The S6 doesn’t need oversized spoilers or aggressive styling to advertise what it is. Its appearance is relatively understated, while the V8, Quattro drivetrain and S6 chassis provide the performance underneath.

Increasingly Difficult to Find

More than two decades after its introduction, clean examples of the C5 Audi S6 Avant have become increasingly difficult to find. The combination of a naturally aspirated V8 and performance-oriented AWD wagon makes this generation particularly interesting to Audi enthusiasts.

For someone who wants something different from the typical performance sedan or SUV, the 2003 Audi S6 Avant offers old-school Audi character, V8 power, Quattro capability and tremendous practicality in one package.

A rare V8 Audi performance wagon with the versatility to be enjoyed year-round.

Vehicle Description

This 2005 Audi S4 Cabriolet combines Audi’s naturally aspirated 4.2-liter V8, Quattro all-wheel drive, and open-top driving in one of the most distinctive performance Audis of the era.

This particular S4 has received an extensive amount of recent mechanical service, preventative maintenance, and restoration work, including major engine, cooling, suspension, drivetrain, fuel-system, electrical, exhaust, and convertible-top work.

Rather than simply addressing one or two items before sale, considerable attention has been given to refreshing the vehicle and correcting many of the age-related maintenance items commonly found on the B6 S4 platform.

4.2L V8 Performance

Under the hood is Audi’s naturally aspirated 4.2L V8, producing approximately 340 horsepower from the factory. Combined with Audi’s legendary Quattro all-wheel-drive system, the S4 delivers immediate naturally aspirated throttle response, strong V8 power, and confident all-season traction.

The factory downpipes have also been removed and replaced with performance downpipes, giving the 4.2L V8 a much more aggressive exhaust note.

Extensive Recent Engine, Cooling & Electrical Service

A substantial amount of recent mechanical work has been completed, including:

• New alternator
• New fuel pump
• Both oil cooler gaskets replaced
• Accessory/serpentine belt replaced
• Belt tensioner replaced
• Idler pulley replaced
• Starter replaced
• Auxiliary radiator replaced
• Fuel filter replaced
• Fresh engine oil service performed

These are meaningful maintenance items on a B6 S4 and represent a significant amount of recent mechanical investment.

034Motorsport Engine & Transmission Mounts

The drivetrain mounting system has also been upgraded with 034Motorsport components, helping reduce excessive drivetrain movement and providing a tighter, more responsive feel.

• 034Motorsport engine mounts — both sides
• 034Motorsport transmission mounts — both sides
• 034Motorsport front snub mount

Transmission & Quattro Drivetrain Service

The automatic transmission and drivetrain have received comprehensive recent servicing:

• Automatic transmission fluid service
• Transmission filter replaced
• Transmission pan gasket replaced
• Rear differential fluid serviced

This work provides fresh fluids and serviceable components throughout important areas of the drivetrain.

Major Front Suspension Refresh

The front suspension has undergone an extensive refresh using high-density suspension components rather than replacing only one or two worn pieces.

Recent suspension work includes:

• Front lower forward control arms with high-density bushings
• Front lower rearward control arms with high-density bushings
• Front upper forward control arms with high-density bushings
• Front upper rearward control arms with high-density bushings
• Front sway-bar end links with high-density bushings
• Front outer tie rods
• Front-end alignment performed after suspension installation

This addresses the major front control-arm, bushing, and steering wear components together and gives the front end a much tighter and more composed feel.

Convertible Top

The convertible system has also received significant attention.

• New soft top installed
• Convertible-top mechanism serviced and repaired
• Power convertible top functioning properly

A replacement soft top is a substantial improvement on an S4 Cabriolet of this age and greatly improves both the appearance and usability of the vehicle.

Exhaust

The restrictive factory downpipes have been removed and replaced with performance downpipes, allowing the naturally aspirated 4.2L V8 to produce a deeper and much more aggressive exhaust note.

Extensively Serviced & Ready to Enjoy

The B6-generation S4 Cabriolet offers a combination that simply isn’t common anymore: a naturally aspirated V8, Quattro AWD, premium German interior, performance-oriented chassis, and power convertible top.

This example has received substantial recent investment where it matters, including a new alternator, new fuel pump, cooling-system work, oil cooler gaskets, starter, belt drive components, 034Motorsport engine and transmission mounts, transmission service, differential service, fuel-system service, major front suspension overhaul, alignment, performance downpipes, and a new convertible soft top.

For someone looking for a B6 S4 Cabriolet, much of the expensive maintenance and age-related work that typically needs attention on these cars has already been addressed.

With the top down and the naturally aspirated 4.2L V8 providing the soundtrack, this S4 delivers the character and driving experience that made this generation of Audi performance cars special.
