Few cars have left their mark on British roads quite like the BMW 3 Series, and the 323 is a prime example of what makes this badge special. The 323 has been available in various model years, most notably throughout the late 1990s and early 2000s – part of the E36 and E46 generations. Compared to rivals like the Audi A4 or Mercedes C-Class from the same eras, the 323 comes up trumps for its rewarding drive and upmarket image. Owners appreciate the 323’s smooth inline-six petrol engine, sharp steering and well-built interior. Practical touches include good boot space, plenty of adjustment in the seats and high-level standard equipment. Later models began to offer more up-to-date tech and better safety features. While the 323 can be more expensive to run than some four-cylinder competitors, it a proper driver’s car.

Later versions from the early 2000s include side airbags and stronger crash structures. The 323's robust build and advanced brakes are both strong points for anyone seeking reassurance on the road.
The BMW 323 is best known for its 2.5-litre straight-six petrol engine, offering a balance of strong performance and smoothness. This engine typically produced between 168–170bhp, and was featured in the E36 (1995–1999) and E46 (1998–2001) generations. All UK 323 models use this engine with minor yearly updates.
Standard equipment on most BMW 323s includes air conditioning, an onboard trip computer, quality stereo with CD player, electric windows and alloy wheels. High-spec models may add cruise control, leather seats or an upgraded audio system. Later E46 cars can feature improved climate control and more advanced displays.
For the 2.5-litre petrol engine in the BMW 323, you can expect combined fuel consumption between 27–32mpg, depending on the model year and whether it’s fitted with an automatic or manual gearbox. This is higher than newer, smaller engines, but in line with other premium six-cylinder saloons of its time.
Inspect for signs of oil leaks around the engine, listen for suspension rattles and look out for any warning lights on the dashboard. Service history is important – especially for regular oil changes and cooling system maintenance. For full peace of mind, consider booking a comprehensive The AA Vehicle Inspection before buying.
Generally, the BMW 323 has a robust reputation provided it’s been properly serviced. The six-cylinder engine is strong, but cooling system issues can appear with age. Interior quality is good, though older models can see wear. Regular check-ups and verifying past care are key to avoiding costly problems down the line.
