2007 Volvo
Sedan
The 2007 Volvo S80 is the second generation of Volvo's flagship full-size sedan, riding on the P3 platform shared with the S60 and XC70. It replaced the boxy first-gen S80 and brought a more contemporary, sculpted look while keeping Volvo's core focus on occupant safety and long-distance comfort. The 3.2L inline-six paired with AWD (branded as AWD or DSTC-equipped FWD depending on trim) made it a genuinely capable year-round luxury commuter. Inside, the S80 punches above its price in ride quality and seat comfort — especially on longer drives. Volvo's reputation for safety hardware is well-earned here; the 2007 model scored well in crash testing and was among the first sedans to offer a pedestrian detection system concept. The cabin materials were premium for the era, though some plastics and electronics haven't aged as gracefully as the chassis. As a used buy in 2024, the S80 is a value-priced luxury sedan that rewards patient, attentive ownership. Parts and independent-shop labor are moderately available, but some Volvo-specific components — particularly ETM, transmission solenoids, and VVTI hardware — can be pricey. Budget for deferred maintenance if buying used.

The VVTI system's oil control solenoids are extremely sensitive to oil quality and sludge. Shortened intervals are cheap insurance against a $400–$1,100 VVTI repair.
Volvo's organic acid coolant degrades and the plastic thermostat housing is prone to cracking, especially after Wisconsin freeze-thaw cycles.
Volvo marks this 'lifetime' fluid but independent shops consistently see transmission wear accelerate past 100k on unserviced units. Change it.
Worn plugs on the 3.2L I6 can trigger misfires that are misdiagnosed as VVTI or coil problems. Replace on schedule.
Blocked drains overflow into the A-pillars and soak the cabin floor, leading to module corrosion and mold. A 10-minute compressed-air flush prevents a very expensive fix.
Volvo's ABS and stability control systems are hydraulically sensitive. Moisture-saturated fluid degrades pedal feel and can trigger C-series chassis codes.
Belt failure on the 3.2L strands the car and can damage the power steering pump. Wisconsin cold makes old belts brittle and tensioners sluggish.
The S80's heavy electrical load (heated seats, DSTC, dual-zone climate) draws the battery hard in cold starts. A marginal battery that passes a summer test will often fail at -10°F.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
The S80 is affordable to buy used but moderately expensive to keep. Routine maintenance on a well-kept example runs $900–$1,400/year. Add deferred-maintenance catch-up costs ($500–$2,000+) if buying a neglected car. Premium fuel, European-spec parts pricing, and Volvo-specific labor mean this costs noticeably more per year than a comparable Japanese or domestic luxury sedan. Find an independent Volvo specialist — dealer rates will push the high end of every estimate.

Same used-luxury price bracket, similar performance and ride quality. Higher parts costs but a deeper independent-shop support network.

Direct competitor — full-size luxury sedan with available AWD (Quattro). Similar ownership cost profile; notorious for oil consumption on V6 engines.

Lower maintenance costs and stronger long-term reliability, but RWD only in this generation limits Wisconsin winter usability without winter tires.

Similar used price, Swedish engineering heritage, comfortable long-distance ride. Parts availability is now a growing concern with Saab no longer in production.
