What the Peugeot 308 SW Actually Is
The Peugeot 308 SW is a compact estate built on the same platform as the 308 hatchback. It's got a longer wheelbase, a rear liftgate, and roughly 590 liters of cargo space with the seats up, expanding to about 1,600 liters when you fold them flat. The SW version exists across three generations so far, and they're not all the same car underneath. That matters more than most buyers realize. If you're shopping for a used 308 SW, you need to know which generation and which engine you're looking at before anything else. The first generation (2007-2013) is built on the PF2 platform shared with the Citroen C4. The second (2013-2021) moved to the EMP2 platform, which is lighter and carries better modern tech. The third generation started in 2021 and is essentially a rebadged 308 II with some reshaped sheet metal. Each generation has distinct failure points, and buying the wrong one for your needs is the most common mistake I see. Here's what most people miss: the second-generation 308 SW's timing belt on the 1.6 THP petrol engine needs replacing at 60,000 miles or 5 years, whichever comes first. Not 60,000 kilometers. Miles. The French service interval notation sometimes confuses non-European buyers. I once saw a guy buy a 2016 model with 42,000 kilometers on the clock, completely convinced the belt was fine. It snapped three weeks later. The engine was destroyed. That belt job costs about 800 to 1,200 euros including parts and labor. Do not skip this check.
Engine Selection
The diesel engines in this car are generally solid if you keep them clean. The 1.6 HDi (90, 110, and 120 horsepower variants) and the 2.0 HDi (150 and 163 hp) are the ones to look for. The 1.6 e-HDi with stop-start is marginally better on fuel but the battery replacement cost is higher and the alternator-starter unit can fail around 120,000 kilometers. Budget an extra 600 to 900 euros if that part gives up. The 1.6 THP petrol engine produces strong power but has that timing belt issue I mentioned, plus it's prone to carbon buildup on the intake valves since it's direct injection. Cleaning those valves costs around 400 euros. The 1.2 PureTech engine in the later models is surprisingly efficient but has a known oil consumption problem in early versions. If you're looking at a 2018 or 2019 1.2 PureTech with high mileage, have someone check the oil level daily for a week before buying. Some owners report burning a liter every 1,000 kilometers without any visible smoke. The 2.0 BlueHDi is the best diesel for high-mileage buyers. It handles 200,000+ kilometers without major issues if the DPF and EGR valve are kept clean. The AdBlue system can develop faults around 150,000 kilometers, and a pump replacement runs roughly 700 to 1,000 euros. Still cheaper than replacing the engine.
What to Inspect Before Buying
Get a pre-purchase inspection from a specialist who actually knows Peugeots. Generic mechanics often treat these like any other French car and miss specific issues. The 308 SW has some idiosyncrasies. The rear subframe mounting points on first-generation models can crack, especially on cars that tow or carry heavy loads regularly. Look for rust around the rear wheel arches and under the spare tire well. Surface rust is normal. Structural corrosion is not. The i-Cockpit in second and third-generation models looks futuristic but the small steering wheel doesn't suit everyone. More importantly, the infotainment screens develop touch response issues over time, particularly in cold weather. Test every function when the car is cold, not after it's been sitting in the sun. The climate control buttons also fail more often than they should, and the replacement requires removing the entire dashboard panel in some cases. The suspension components on the EMP2 platform wear at a normal rate but the front control arm bushings tend to go first. You'll feel it as a vague steering feel over bumps. Replacing those costs about 300 to 500 euros depending on whether you go with original or aftermarket parts. Don't cheap out on those bushings. Aftermarket ones wear twice as fast on these cars.

Maintenance Costs and Reliability Reality
A annual service on a 308 SW runs 250 to 400 euros at an independent specialist, not the dealer. Dealer pricing will add about 40 percent. Oil changes every 15,000 kilometers or annually are standard. Some owners run 10,000 kilometer intervals and it doesn't hurt the engine. The 2.0 HDi and 1.6 HDi are tolerant of slightly longer intervals if you use good quality synthetic oil. Tyres are 16 to 18 inch depending on trim. Expect 200 to 350 euros per set at mainstream brands. Brake pads and discs last 40,000 to 60,000 kilometers on the front, longer on the rear. The regenerative braking on hybrid versions wears the mechanical brakes less but adds complexity. The 308 Hybrid only comes in the third generation, so it's a newer purchase with higher depreciation but lower running costs if you can charge it regularly.
Resale Value and Depreciation
Peugeot holds value worse than German rivals in most markets but better than some Italian options. A three-year-old 308 SW loses roughly 35 to 40 percent of its original price. By year five, you're looking at about 50 to 55 percent depreciation. The diesels hold slightly better because fleet buyers dominate the used market for these cars. Petrol versions depreciate faster but that also means you pay less upfront for the same hardware. If you're in Italy or a Spanish-speaking market, "usata" just means used. The 308 SW usata market is active because these cars are practical, reasonably comfortable, and not expensive to fix once you know what to look for. The biggest price difference comes from trim levels. The Allure and GT trims command premium prices but the equipment differences don't justify the markup for most buyers. A loaded Active or Premium is usually the smarter purchase.
Common Problems by Generation
First generation (2007-2013): Timing belt on 1.6 THP engines, rear subframe cracks, iMotion gear selector failures on automatics, air suspension issues on higher trims with that option. The EGC automatic transmission is slow and not particularly reliable past 150,000 kilometers. Manual gearboxes are fine. The 6-speed automatics introduced later are better but still not in the same league as a proper dual-clutch or conventional torque converter. Second generation (2013-2021): Timing belt on 1.6 THP, 1.2 PureTech oil consumption, DSG-like EGC6 transmission solenoid failures, touchscreen glitches, window regulator failures on the driver's door, and occasional electrical gremlins from the CAN bus network. The EGC6 is the most problematic component in the later second-gen cars. If the car jerks during low-speed shifts or shows a warning light, walk away. Repair involves dropping the gearbox and replacing the mechatronic unit, which runs 1,500 to 2,500 euros. Third generation (2021-present): Still relatively new so long-term reliability data is thin. Early models had some software bugs that were resolved with updates. The main concern is the hybrid system's high-voltage battery warranty coverage and whether any remaining battery degradation exists on used examples. Get the full service history and confirm all recalls were completed.
Practical Ownership Tips
Keep the service records organized. French cars tend to have gaps in documentation, and that makes diagnosis harder when something goes wrong. A clear service history adds roughly 5 to 10 percent to resale value and makes finding a buyer significantly easier. Buy a diagnostic tool that supports Peugeot's proprietary systems. OBD2 readers that only show generic codes won't tell you much about the transmission, air conditioning, or advanced driver assistance systems. A good scanner like Lexia or Diagbox (or a legitimate alternative) can read fault codes across all modules and help you verify what the seller claims. This takes about 20 minutes and could save you a thousand euros in unexpected repairs. The cargo area in the SW is genuinely useful for groceries, luggage, or whatever you need to carry. The load floor is at a comfortable height for most people. The split-folding rear seats (60/40) are convenient but the latches can break if you're not careful when folding them back up. Engage them gently and listen for the click. Broken latches are a 50-euro fix at a parts supplier but annoying to live with.
Insurance groups for the 308 SW range from about 10 to 25 depending on engine and trim. The diesel models sometimes sit in slightly higher groups due to repair cost averages. Full comp coverage is usually reasonable on older models since the car's value is modest. The hybrid version will cost more to insure and more to repair if damaged due to the high-voltage components. There's no perfect used compact estate. The 308 SW is practical, reasonably comfortable on long drives, and cheap enough to own once you avoid the known pitfalls. Focus on the engine choice, check the maintenance records, and verify the timing belt status on any petrol model. Everything else is secondary.
