Put a used Volkswagen Passat beside a used BMW 3 Series in Ireland and the price gap looks small: about €2,000 at the median. The gap that actually matters is on the odometer. The typical Passat for sale has done roughly 75,000 km more than the typical 3 Series — because most Passats were bought by fleets and reps, and most 3 Series were bought by someone who wanted one.
The short answer: on Autoza in September 2026 the median Passat is €15,950 with about 195,000 km on it, nearly all diesel and only 35% automatic. The median 3 Series is €17,999 with about 120,000 km, 95% automatic, and a big share of them are 330e plug-in hybrids. Buy the Passat for space and the lowest cost per kilometre; buy the 3 Series for a younger, lower-mileage automatic. Either way, check the exact gearbox and engine before you pay — that decides more than the badge does.
Why is the mileage gap the whole story?
Both are 2.0-litre diesel saloons in the trade's eyes, so why does one turn up with 195,000 km and the other with 120,000 km? Fleet history. The Passat was Ireland's default company car for a decade — sales reps, pharma field staff, anyone doing Cork to Dublin twice a week. Those cars cover 30,000–40,000 km a year and land on the used market with the clock already high. The 3 Series was more often bought privately or on a personal lease, and driven like a personal car.
Two things follow. A high-mileage Passat isn't automatically a bad Passat — motorway kilometres are the gentle kind, and the 2.0 TDI takes them well when it's serviced. But mileage is the first thing your buyer will look at when you come to sell, so a 200,000 km Passat will always be a slow resale, however well it drives.
- Passat, 2013–2015 cars: median €6,990, typically around 245,000 km, almost all manual.
- Passat, 2016–2018 cars: median €14,950, around 164,000 km.
- Passat, 2020–2022 cars: median €20,450 — but still around 211,000 km. Those are ex-fleet cars coming off three- and four-year cycles.
- 3 Series, 2015–2018 (F30): median €17,833, around 134,000 km.
- 3 Series, 2019–2025 (G20): median €27,950, around 106,000 km.

What does €16,000 buy in each?
Set a budget of €14,000–€18,000 — the heart of both markets — and the two cars split cleanly.
| €14k–€18k budget (Autoza, Sept 2026) | VW Passat | BMW 3 Series |
|---|---|---|
| Median asking price | €16,950 | €17,450 |
| Typical years | 2017–2021 | 2015–2018 (F30) |
| Typical mileage | About 160,000 km | About 121,000 km |
| Automatic share | Roughly 6 in 10 | All of them |
| Fuel | Nearly all 2.0 TDI diesel | Mostly petrol and 330e plug-in hybrid; the odd 320d |
| What you're really buying | A newer, bigger car with fleet miles | An older, lower-mileage premium car with a proper automatic |
The surprise for most buyers is the fuel row. At this money the 3 Series stock isn't diesel-heavy — it's 320i petrols and 330e plug-ins, most of them 2016–2018 F30s. If you want a 320d under €18,000 you're into older F30s, and that brings you to the N47 timing-chain question (below). For a 2.0 TDI diesel at this budget, the Passat is the easier find.
Below €10,000 the Passat is the only realistic option of the two: a 2013–2017 manual diesel around €6,990 with very high mileage. A sub-€10k 3 Series exists, but it's a 2010–2014 car and needs a specialist's eyes before you hand over money.
Which engine and gearbox should you look for?
Passat: the 2.0 TDI, and mind which DSG
Almost every Passat on the Irish market is a 2.0 TDI (150 hp, occasionally 190) from the B8 generation (2015–2023) or a late B7. The engine is sound at high mileage. The gearbox is where used Passats go wrong, and it depends on the box, not the badge:
- Seven-speed dry-clutch DSG (DQ200) — fitted to the 1.6 TDI and 1.4 TSI, and found on some early B8 cars. Mechatronic and clutch failures around 110,000–140,000 km are well documented; budget €1,500–€2,500 for a mechatronic repair (2026 prices). VW specifies no oil change for this unit, so judge it on symptoms — juddering from a standstill, hesitation pulling away uphill.
- Wet-clutch DSG — the six-speed DQ250 on early 2.0 TDIs and the seven-speed DQ381 from the 2019 facelift. Far more durable, but it wants a fluid and filter change every 60,000 km. Look for the stamps, and confirm the gearbox code on the car rather than assuming from the engine size.
- Six-speed manual — the majority of cheaper Passats, and the least to go wrong. A manual median of €13,950 against €18,950 for an automatic is a big premium for losing a pedal.
Also confirm the EGR cooler recall (reference 23R6) has been done on 2015–2018 TDIs. Our Passat common faults guide has the full checklist, and the Golf faults guide explains the dry-versus-wet DSG difference in more depth — it's the same hardware.
3 Series: a 318d/320d from 2015 on, or a 330e
- 320d / 318d with the N47 engine (F30, 2012–2015): the rear-mounted timing chain can stretch and fail from about 100,000 km, and because it sits at the back, the engine comes out to fix it — €3,000–€6,000. Only buy one with documented chain replacement.
- 320d / 318d with the B47 engine (F30 facelift from 2015, all G20): the one to have. No inherited chain problem; watch AdBlue NOx sensors above 100,000 km (€200–€800).
- 330e plug-in hybrid: the F30 version (2016–2019) has a 7.6 kWh battery and an official electric range of about 40 km (BMW, NEDC); the G20 (2019–2023) has 12 kWh and 59–66 km WLTP; the 2024 update jumped to 19.5 kWh net and 85–101 km WLTP. Winter range is lower on all three. Median asking price for a 330e on Autoza is €18,950, spanning 2016 to 2025 cars.
- The ZF eight-speed automatic is on virtually every 3 Series here. It's a torque-converter box, not a dual-clutch, and it lasts — provided the fluid is changed. BMW calls it lifetime fill; independent specialists budget a €300–€500 service every 60,000 km or so.

What do they cost to run in Ireland?
Day to day, the two diesels are closer than the badges suggest. Motor tax is band-based, so a 2.0 TDI Passat and a 320d of the same era usually pay much the same; the 330e is cheaper again.
| Annual cost (2026) | Passat 2.0 TDI | BMW 320d | BMW 330e |
|---|---|---|---|
| Motor tax, registered 2008–2020 | €200–€280 (Bands A4–B2; most at €200) | €200–€280 (most at €200) | €170 (Band A1) |
| Motor tax, registered 2021 on | €190–€210 (WLTP bands) | €190–€210 | €140 |
| Real-world economy | 5.2–6.0 L/100 km | 5.0–6.0 L/100 km | Depends entirely on charging habit |
| Gearbox service | DSG fluid + filter every 60,000 km (wet-clutch only) | ZF service €300–€500 | ZF service €300–€500 |
| NCT (yearly once the car is 10) | €60 full / €40 re-test | €60 / €40 | €60 / €40 |
| Big-ticket risk | DSG mechatronic €1,500–€2,500 | N47 chain €3,000–€6,000 (pre-2015 only) | Battery health — get it checked |
The band depends on the CO₂ figure on the car's VRC and its first-registration date, so check the exact car with our motor tax calculator; the full tables are in the 2026 motor tax guide. Insurance is the wildcard: Ireland has no official insurance-group table, premiums track the driver far more than the car, and BMW parts and labour cost more when something does go wrong — our car insurance guide has the ways to cut it.
Space, boot, comfort — and the badge
This is where the Passat earns its keep. The B8 saloon's boot is 586 litres; the 3 Series saloon's is 480 litres, and the 330e gives up another 100-odd litres to its battery, at 375 litres. Rear legroom follows the same pattern — the Passat is the car for two child seats and a teenager in the middle, the BMW the car for two adults who don't mind sitting close. A Passat Estate, if you can find one, is the most practical car in this whole comparison.
The BMW answers with the drive. Rear-wheel drive, a sharper steering rack and that eight-speed auto make it the car you'd pick for a long run down the M8. It also holds the badge premium at resale: a 2015–2018 3 Series still asks €17,833 at the median where a 2016–2018 Passat asks €14,950 — and the BMW has 30,000 km fewer on the clock for that money. Depreciation has largely been paid on both by now, so the gap is roughly what the market will still pay for the roundel.
Verdict: which one should you buy?
- Family, two car seats, holiday luggage: Passat. Take a 2019-or-later 2.0 TDI with the wet-clutch DSG or a manual, accept the mileage, and put €300–€500 aside for a specialist inspection and gearbox service on day one.
- Long-distance commuter (Athlone–Dublin, Limerick–Cork): either, but the 320d B47 (2016 on) is the nicer place to spend two hours a day, and its mileage will be lower. If the budget stops at €15,000, the Passat 2.0 TDI is the safer diesel.
- Dublin driver with a driveway: a G20 330e. Charge it nightly, do most of the M50 crawl on the battery, and tax it for €140–€170 a year.
- Rep who pays their own fuel: Passat 2.0 TDI manual — the cheapest car per kilometre here, as long as a dry-clutch DSG hasn't slipped onto your shortlist by accident.
- You just want the BMW: fair enough. Buy a post-2015 B47 diesel or any G20, insist on full service history, and skip the cheap N47 no matter how clean it looks.
Whichever way you go, take the 25-point used-car checklist to the viewing.

Frequently Asked Questions
Is a used Passat or BMW 3 Series cheaper in Ireland?
On Autoza in September 2026 the median asking price is €15,950 for a Passat and €17,999 for a 3 Series — about €2,000 apart. But the typical Passat has around 195,000 km on it against about 120,000 km for the 3 Series, so the BMW is the younger car per euro.
Why do used Passats have such high mileage?
Most were company or fleet cars driven 30,000–40,000 km a year. On Autoza, even 2020–2022 Passats show a median of around 211,000 km. Motorway miles are the gentle kind, but they hit resale value hard.
Which Passat DSG gearbox should I avoid?
The seven-speed dry-clutch DQ200, fitted to the 1.6 TDI and 1.4 TSI and found on some early B8 cars — mechatronic failures around 110,000–140,000 km cost €1,500–€2,500. The wet-clutch boxes on the 2.0 TDI (DQ250, and DQ381 from 2019) are far more durable if the fluid was changed every 60,000 km.
Is the BMW 320d reliable as a used car?
The B47-engined 320d (F30 facelift from 2015 and every G20) is a solid high-mileage diesel. The earlier N47 (2012–2015) has a rear timing chain that can fail from 100,000 km — a €3,000–€6,000 engine-out repair — so only buy one with proof it was replaced.
How much is motor tax on a Passat 2.0 TDI vs a BMW 3 Series?
Most 2.0 TDI Passats and 320ds registered 2008–2020 pay €200–€280 a year, with the majority at €200 (Band A4). The 330e plug-in hybrid pays €170 if registered up to 2020 or €140 from 2021 on. Check the CO₂ figure on the VRC to be sure.
Is the BMW 330e worth buying used?
Yes, if you can charge at home and most trips are short: the G20 (2019–2023) is rated at 59–66 km WLTP on electric, the F30 (2016–2019) at about 40 km. Median asking price on Autoza is €18,950. Have the battery health checked, and remember the boot shrinks to 375 litres.
