BMW 3 Series2016

• **Petrol engine choice matters hugely** — N20/N26 turbo engines prone to timing chain rattle, carbon buildup, and turbo issues; naturally aspirated 320i or 328i safer bets if available.
• **Price sits mid-market for age and mileage** — €13,995 median is fair value; petrol 3 Series not commanding premiums, so avoid overpaying for high-spec trim without proven service history.
• **Cold-start rattle is a red flag** — Start engine from cold before test drive; any metallic noise signals imminent chain tensioner work (€800–€1,200 labour). Deal-breaker unless recently done.
• **Request full service records and emissions testing** — Carbon buildup on direct-injection valves causes rough idle and hesitation; proof of professional decarbonising (€400–€600 job) gives confidence. Check last NCT pass date.
• **Verify turbo condition in N20/N26 models** — Wastegate actuator sticking causes boost lag and reduced power; any hesitation under acceleration warrants independent inspection before committing.
