Frequently asked questions
Is the BMW 3 Series reliable?
The G20 3 Series scores above average for reliability in owner surveys. The B48 2.0 petrol engine is well proven — just keep up with scheduled servicing.
What is the real-world mpg of the 320i?
Expect 36–42 mpg in mixed driving. Motorway cruising at 70 mph will beat the official 42.8 mpg figure.
Should I buy the 320i or 320d?
The 320d suits high-mileage drivers with better economy and torque. For under 12,000 miles a year, the 320i petrol is cheaper to buy and simpler to own.
