What owners say
"Overall, owners of the 2021 BMW 3 Series are extremely pleased with their cars, praising the exceptional handling, powerful performance, luxurious interior, and a host of safety features. Many admire the fuel economy and trunk space as well. However, a few drivers noted concerns with the audio system and mechanical noises that affected their purchase decisions."
It took weeks to find my car, but once I saw it I had to have it. I found the perfect 2021 330i. The car has everything I wanted and more.
July 4, 2026Extremely responsive car with Good fuel economy. Driving assist system is extremely helpful as well. The audio is somewhat lacking (speakers) but NOT a deterrent to the car at all.
January 21, 2025The car is beautiful, but I couldn’t buy it because it was making noises when I drove it. I can’t buy a car that I need to bring to the shop as soon as I get it.

November 28, 2025Just really like the 3 and 4 series. Combination of performance , reliability and ride are great.
April 3, 2025Wow! Excellent handling, acceleration, luxurious interior, and tons of safety/convenience features. All with an enormous trunk, sunroof, and 165 lbs of luggage roof rack capacity. Very glad I purchased this 330i xdrive as my first BMW.
April 17, 2024The m340 is superb! The handling, power, tech, comfort, and appearance are unparalleled with any car in its class. I loved my 2018 BMW 340ix and couldn’t envision better, but it truly is night and day. Well done BMW on this m340 home run.
December 18, 2020The best daily driver to date. All the power you need and more. AWD is amazing on this car. Sound car with tons of power but also with the mild hybrid system easy to get upper 30s for MPG on highway commutes.
