The CarGurus verdict
The E90 3 Series is a fantastic car to drive and boasts superb handling and a great choice of muscular and economical engines; its appeal is boosted further by its smart looks and a truly aspirational image. That said, there are quite a few big issues that these cars can have, especially if they aren’t maintained well, so it’s imperative to find a well cared-for example to minimise the risk.

What is the BMW 3 Series?
The BMW 3 Series E90 is part of a long line of what is BMW’s most successful model. It was sold between 2006 and 2013 and can be found in saloon, Touring estate (E91), coupe (E92) and cabriolet (E93) forms. All were less conservative than those that had gone before, boasting more individualistic styling, both inside and out, even before it was given a cosmetic facelift in 2009.
Beneath the skin, there were changes afoot, too. When the new BMW E90 3 Series was being developed the company was in the process of moving to downsized engines, so the six-cylinder powerplants that had marked out older models were available only in the most potent versions. More common-or-garden 3 Series diesel models used turbocharged four-cylinder engines for the first time.
This generation was replaced in 2012 by the F30-generation BMW 3 Series.

How practical is it?
Practicality is decent enough, if not outstanding. There’s less space in the back of the E90 3 Series than there is in the contemporary Mercedes C-Class, and both are bested by more mainstream rivals like the Volkswagen Passat and Mazda 6.
Having said that, nobody will feel cramped inside a 3 Series unless they’re either extremely tall, or extremely broad. And if your need is to fit two child seats into the rear seats, you’ll have no issues – though three will probably be a struggle.
The same goes for the 460-litre boot – it isn’t quite as vast as that of the Passat, but neither is it small by the standards of the class. Certainly, you should be able to fit in enough luggage for a day out with the kids, though if you regularly travel heavy on your holidays, the Touring estate version might be a better bet.

What's it like to drive?
The move to four-cylinder engines didn’t stop the 3 Series being great fun to drive, though. In fact, you won’t find an E90 that isn’t, helped in large part by its rear-wheel drive layout. However, we would advise caution if you’re thinking about choosing one of the racy-looking M Sport versions; these came with stiffer suspension and larger alloy wheels, which make the ride uncomfortably stiff. Stick with an SE if you can live with the plainer looks – and you value a comfortable ride.
Whatever your trim or wheel set-up, you will find the performance from the six-cylinder petrol and diesel models (the 326i, 330i and turbocharged 330d, 335d and 335i) much more satisfying than those of the four-cylinder cars, though as we've said the more lowly engined cars still deliver a great driving experience.

Technology, equipment & infotainment
As for which engine to choose, there’s a huge range from which to take your pick – from some particularly efficient diesel engines right up to fire-breathing V8 petrols (albeit only in the M3). However, for most people, the petrol 320i or diesel 320d should get the job done, and then some. Bad news for those looking for all-wheel drive – although xDrive models of the E90 were sold in other countries, none were on sale in the UK. Both six-speed manual and automatic gearboxes were available.

BMW 3 series running costs
The most economical version of the 3 Series is the 320d EfficientDynamics, or ED for short. You should see around 55-60mpg from one of these in everyday driving, and as it sits in VED band B, it’s cheap to tax as well.
If you’d rather have a petrol model, the 318i should see around 40mpg in day-to-day driving, while the 320i should achieve around 2 or 3mpg less than this. Of course, if it’s the M3 you’re after, you’ll have to be prepared for fuel consumption in the region of 20mpg or less.
The 3 Series uses a system BMW calls condition-based servicing. What this means is that it doesn’t have a set service schedule, but instead servicing must be carried out whenever it is deemed necessary by the car itself. Sensors within the engine monitor the condition of the oil and other systems, and when a service is required, an indicator on the dashboard tells the driver.
As a result, there’s no hard and fast mileage at which a 3 Series should have been serviced, but as a general rule, you’ll want to look for servicing that’s been carried out every 10-20,000 miles. As this version of the 3 Series is more than 3 years old, it benefits from BMW’s Value Service scheme, which means a small service should cost between £120 and £200, while a large one should cost a little over £300.
All 3 Series models feature a timing chain, rather than a timing belt, which you shouldn’t need to worry about replacing – in theory.

BMW 3 series reliability
As above, a timing chain shouldn’t need to be replaced, but almost every 3 Series engine has been known to suffer from timing chain issues involving stretching of the chain, which results in severe engine damage. It’s thought the problem is exacerbated by neglected maintenance – missing services, or filling the engine with cheap oil or the wrong grade. That’s why it’s vital to make sure you only buy a 3 Series with a complete record of regular servicing carried out by a BMW dealer or an independent specialist.
Look out for white smoke on acceleration on diesel models; this could point to a blown turbo, which is not unknown. You’ll also want to check there are no lights on the dashboard that could point to a blocked particulate filter, and beware dual mass flywheels, which are known to shatter without warning and are costly to fix.
Issues with injectors and/or coils can crop up on petrol models, and again, these aren’t cheap to sort out. A problem will be obvious because the car won’t run right, and there will probably be a warning light on the dashboard.
Steering racks are known to leak fluid, and not many owners check and top up the fluid level regularly. So have a look at the reservoir to see if it looks low, and if you can see the rack itself underneath the car, look for signs of leakage around the seals.
- The blisteringly quick M3 came in saloon, coupe and convertible form, and now looks like pretty good value on the used market. You get a spine-tingling 414bhp V8 engine. pumped-up looks and a high specification – not to mention some of the best handling out there. Yet prices start at just £12,000. In short, it’s a baby supercar for family hatchback cash.
- If you’ve got a bit of extra stuff to carry around, you might be tempted by the Touring, which is BMW parlance for the estate version. While the Touring is undoubtedly more practical than any other of the version of the 3 Series, though, its rakish looks mean its boot is a touch on the small side compared with frumpier but more capacious alternatives like the Volkswagen Passat.
- In 2010, BMW revealed a high-efficiency version of the 320d, badged EfficientDynamics, or ED for short. Compared with the standard 320d, the engine was detuned slightly, the suspension was lowered to improve aerodynamics, the gearing was tweaked and aerodynamic wheel covers were fitted, all in order to lower fuel consumption and CO2 emissions.
- For motorway driving: Long-distance drivers will love the 320d; its mix of flexible performance and low fuel consumption make it an ideal companion for slugging up and down the motorway.
- For the city: If most of your driving is done in town, keep things simple with the 318i. There’s more than enough performance on tap to keep up with traffic, mpg figures should be very reasonable, and there are no diesel particulate filters to clog up.
- As an all-rounder: If your driving involves a bit of everything, the 320i is a great bet, with the flexibility you’ll want on the motorway and the simplicity of a petrol engine.
- For a bit more poke: Want a fast sports saloon without the fuel and maintenance costs of the full-blown M3? In that case the 330i and 335i both boast gutsy straight-six engines, the latter of which is turbocharged. Granted, either will use more fuel than a standard 320i, but if you can live with that, they’re the pick of the range.
- For open air thrills: the 325i Convertible is one of the best cars of its type, with a folding hard-top roof for added security, and a creamy smooth straight-six engine that provides more than enough power for boulevard cruising.
