Recalls & safety

Pros & cons
Pros
- Last-generation naturally-aspirated N52 inline-six is smooth, characterful and avoids the turbo hardware of pricier 335i siblings.
- Classic rear-drive 3 Series balance makes it one of the more engaging compact sport sedans of its era.
- Widely regarded as one of the safer used BMW engines, with strong specialist and parts support.
Cons
- Premium-brand maintenance, parts and labor cost more than mainstream rivals.
- Age-related oil leaks from the valve-cover and oil-filter-housing gaskets are near-universal upkeep on higher-mileage cars.
- Cooling components (water pump and thermostat) are wear items that need preventive replacement to avoid overheating.

Depreciation
Move your cursor along the line to see the estimated value for any year.
This listing sits above the typical depreciation curve. Common for heavily-optioned cars and for 2021-2023 model years (pandemic-era pricing); the curve is anchored at base MSRP, which excludes options.
Curve anchored at the entry-trim base MSRP ($32,400). Higher trims started higher (up to $43,200), and options added more.
The curve's data ends 10 years in, so the line levels off after that. Treat the tail as a floor, not a forecast: asking prices for older cars depend mostly on condition, mileage, and the current market, and often sit well above it.
