Introduced for the 2014 model year, the F33 was the first convertible to wear the 4 Series badge, splitting from the long-running 3 Series lineup. Its defining feature is a three-piece retractable hardtop, which offers the security and quietness of a coupe when closed. This was the last BMW convertible of this size to feature a hardtop before the subsequent G23 generation returned to a soft-top. Engine choices ranged from the turbocharged 4-cylinder in the 428i and 430i to the potent inline-6 in the 435i and 440i.
The F33's appeal is its dual-purpose nature. It's a comfortable and stylish grand tourer that doubles as a closed coupe, making it a practical choice for year-round driving. Enthusiasts prefer the more powerful and smoother N55 and B58 inline-6 engines found in the 435i and 440i, especially when paired with the desirable M Sport package. As a modern car, it's packed with technology that still feels relevant today.
The market for the F33 is firmly in the depreciation part of its curve. With an average sale price around $23,000, these cars represent a strong value proposition. Early, higher-mileage 428i models anchor the low end of the market, while late-model, low-mileage 440i M Sport variants command the highest prices. It's not a classic yet, but it's a popular choice for buyers seeking a modern, fun, and stylish convertible without a huge price tag.
Buying Tips
- Test the folding hardtop several times. It should operate smoothly and without any unusual noises, as repairs to the complex mechanism are costly.
- On early 428i models with the N20 engine, listen for a high-pitched whine that could indicate timing chain guide failure. Check the service history for preventative replacement.
- Inspect the trunk and footwells for dampness. Clogged roof drains can lead to water ingress and potential electrical issues.
- The inline-6 models (435i/440i) are more desirable and hold their value better. They offer a significant performance upgrade over the 4-cylinder.
- Check for common oil leaks from the oil filter housing and valve cover gaskets, which can affect both engine types.
Prices for the F33 4 Series Convertible range from about $5,300 for early high-mileage cars to as much as $67,000 for late-model, low-mileage examples.
