Price range
P75 → P25 of asking — the middle half of listings at that age sits inside this band. Outliers above and below excluded.
Down payment
MAS Notice 642 LTV cap applied to the age's median asking: 30% when OMV is up to S$20k, 40% above. Max loan tenure 7 years. Rows marked * mix both OMV buckets — we display the conservative 40% figure so the quote never under-states what a luxury-OMV listing at that age would actually require.
Availability
High when this age's listing share is ≥1.5× the model's uniform expectation, low when ≤0.6×, medium otherwise. Model-relative, so an evenly-spread model lands all-medium.

Resale strength
100 − 3× annualised tangible-decay (COE-stripped). Fitted from each variant's asking-price-by-age regression then averaged at model level.
Peer set
Every same-segment model with ≥5 active PARF listings whose variants fit a depreciation curve. Practicality isn't plotted — it's a body-shape constant within the segment, so it would be the same for every dot.

BMW 3 Series — 7th gen G20/G21 (2019-present)

Verdict

The reliability rebound of the 3-Series line — petrol/PHEV ranked 2nd in executive class with a 97.5% reliability score in the 2024 What Car? survey. M340i (B58 inline-six) is the durable hero; 330i (B48) the same oil-discipline rule as every B48 platform. Key paperwork checks: 2020-2022 starter-motor recall (24,732 UK BMWs incl. G20/G21) for magnetic switch wear / short circuit risk, and IBS (Integrated Braking System) recall on early G20 affecting pedal feel + braking power. iDrive 7 launched on G20; cleaner than the iDrive 6 era.

What's good

  • M340i (B58 inline-six) — the modern BMW inline-six everyone wants — same B58 engine family as X3 M40i / 540i / 740i / M240i / 440i. No chain story, no HPFP weakness; comfortable to 200k+ km when serviced. The most-confident pick on the chassis.
  • Both the starter-motor and braking-system recalls already done — both recalls are real BMW-issued fixes that take care of safety-critical items. Closed paperwork converts the headline G20-era flags to non-issues.

What to watch

  • A 2020-2022 build where the starter-motor recall hasn't been done — magnetic-switch wear can short-circuit / overheat. Cheap fix at the dealer but paperwork is non-negotiable; verify via BMW VIN check.
  • B48 330i / 320i with service book showing only the 30k km BMW oil interval — same chain-guide-life rule as every B48 platform (X1 F48 / X3 G01 / 1-Series F40 / 4-Series F32). The recommended interval is too long for SG heat; treat as if a refresh is on the horizon.

BMW 3 Series — 6th gen F30/F31 (2011-2019)

Verdict

Mechanically the same B-engine family as the F22 / F32 / 5-Series — every check carries over. Pre-Feb 2015 320i / 328i (N20/N26) carry the chain-guide recall — verify the work was done. Post-LCI 340i (B58 inline-six, 2016+) is the durable hero. 330e plug-in hybrid adds HV battery + e-motor as additional age-related risks. F31 wagon body is a SG rarity; F30 sedan is the mainstream pick.

What's good

  • Post-LCI 2016+ 340i with B58 inline-six — the B58 replaced the N55 at the LCI and is widely regarded as one of the most-durable modern BMW sixes; no chain story, no HPFP weakness. The most-confident pick across the F30/F31 platform.
  • A pre-2015 320i / 328i (N20/N26) with the chain-guide fix done under BMW's warranty — the recall fix is real and BMW covered it. A receipt for the work converts the headline gen risk to a non-issue (same as F22 / F32).

What to watch

  • A 2012 - Feb 2015 320i / 328i (N20/N26) with no chain-guide replacement receipt — same affected build window as F22 / F32 / F10. Cold-start metallic rattle is the warning sign; failure cascades to bent valves + cracked pistons. Walk unless paperwork is in hand.
  • A B48 330i / 320i (post-LCI) with oil changes stretched to BMW's 30k km interval — the recommended interval is too long for chain-guide life in SG heat; same X1 F48 / X3 G01 oil-discipline rule applies. Treat as if a refresh is on the horizon.

BMW 3 Series — 5th gen E90/E91/E92 (2005-2013)

Verdict

N52 inline-six (NA, 325i / 328i / 330i) is the durable hero — no chain story, no HPFP weakness, comfortable to 250k+ km when serviced. N54 (335i 2007-2010 twin-turbo) carries a 35-45% HPFP failure rate — verify the BMW HPFP extended warranty (10yr/120k mi) was used. N55 (335i 2011-2013) drops that to 15-20%. Late-gen N20 (320i / 328i 2012-2013) inherits the chain-guide story documented on F22 / F30. M3 (S65 V8, E92/E93) is its own world — bearings + rod-bolt service is part of ownership.

What's good

  • N52 inline-six 325i / 328i / 330i with full service history — the durable hero of the E9x gen; naturally aspirated, no HPFP, no chain weakness. The low-stress buy on the chassis; a clean 328i is materially less risky than any turbo trim.
  • 335i (N54) with documented HPFP replacement under BMW's 10yr/120k mi extended warranty — the HPFP work is the most-likely thing you needed BMW to cover; receipts convert the headline N54 risk to a non-issue. Multiple-pump replacements over the life are normal for these cars.

What to watch

  • N54 335i with vague HPFP history at 10+ years — the original HPFP failure rate was 35-45%; a car that's never had it replaced is statistically due. S$2.5-3.5k each (some cars get two over a lifetime). Walk unless the asking prices it in.
  • Late-gen N20 (320i / 328i 2012-2013) with no chain-guide work on record — same pre-Feb 2015 N20 chain story documented on F22 / F30. The BMW SG service campaign is now closed, so authorised-dealer paperwork showing the chain-guide work is the only signal. Walk unless verified.

Common questions about the BMW 3 Series

How much does a used BMW 3 Series cost in Singapore?
Most used BMW 3 Series on the market are around 9 years old, asking roughly S$39k–S$50k (typically about S$46k). That's the age with the widest choice — and the most sellers competing, so it's where you'll have the most room to bargain.
How much does a used BMW 3 Series depreciate per year?
A used BMW 3 Series loses value at a fairly steady pace — around 16% a year — with no real plateau. An older one costs less but keeps falling at much the same rate, so there's no single 'bargain age': buy on price and condition, not on timing.
Is the BMW 3 Series reliable?
In our read, the BMW 3 Series scores 55 out of 100 on brand reliability. That still varies by generation and how the individual car was looked after, so always check the service history before you commit.
What should I expect to pay for a used BMW 3 Series with a given mileage?
It depends on the exact variant, age and mileage — a higher-mileage car should ask less. Use the price modeller on this page to get a fair-price range for a specific age and mileage, so you know what to offer.
Where do these BMW 3 Series figures come from?
They're worked out from current used-BMW 3 Series listings in Singapore — asking prices, mileage and registration years — not past transaction prices. We refresh them regularly, and we flag thin data rather than guess.
