All engines for the 3 Series come with Efficient Dynamics energy-saving measures, so whichever you choose, it's among the class leaders for fuel economy and emissions. There are five petrol and five diesel engines, and performance ranges from capable to colossal. Our favourite is the 174bhp 320d, which is strong and smooth, with minimal running costs.

The 3 Series is the sharpest car to drive in its class. Sublime body control and tenacious grip give it poise through corners, while the steering is accurate and communicative. The firm-but-fair suspension makes you aware of low-speed bumps and coarse surfaces, but it's never uncomfortable.

The 3 Series is a quiet car and makes a great long-distance cruiser. You can tell which fuel the diesel uses, but engine noise is always well isolated and you barely hear it once you're settled on the motorway. Road and suspension noise are subdued over even the worst road surfaces. Some wind can be heard at high speeds, though.

The 3 Series has a higher starting price than the rival Audi and is similarly priced to the equivalent Mercedes. It's hugely desirable, however, so it holds its value extremely well. The 2.0 diesel’s low running costs will make it the most popular choice – it returns nearly 60mpg and falls into the lowly 18% bracket for company car tax.

This car oozes class. Everything has a solidly constructed, built-to-last feel, while the cabin materials are top quality. Numerous trim combinations allow buyers to tailor the interior to their own tastes. Mechanical reliability won't be a concern, either.

The 3 Series scores well for safety, with twin front, side and curtain airbags, run-flat tyres, electronic brakeforce distribution and stability control as standard across the range. It was also awarded a maximum five-star rating in Euro NCAP crash tests, while deadlocks make life difficult for thieves.

A good range of adjustment for both the driver’s seat and steering wheel means people of all shapes and sizes can find a suitable position, but the manual seat mechanism is awkward. The standard dashboard layout features simple stereo and heater controls, while the optional sat-nav brings BMW's iDrive central controller.

There's enough legroom for the longest limbs in both the front and back seats. Those over six-feet tall might brush their heads against the ceiling in the rear, however. The boot is big, but not as large as those of some competitors, and it's not as well shaped as an Audi A4's.

Entry ES models come with alloy wheels, a CD player, four electric windows and air-conditioning, but you have to upgrade to SE to get dual-zone climate control and reversing sensors. Range-topping M Sport cars feature a muscular bodykit, larger alloy wheels, lowered suspension, sports front seats and brushed aluminium interior trim.
