If you've been searching for a 2021 BMW 3 Series 330i Sedan for sale in San Diego, CA, this clean white example at Siry Motors San Diego deserves your full attention. With 68,697 miles on the clock, this rear-wheel-drive sports sedan hits the sweet spot of modern features, proven performance, and everyday practicality — all in one of Southern California's most desirable luxury segments.

About This 2021 BMW 3 Series 330i

The G20-generation 3 Series, launched for 2019, represents one of BMW's strongest returns to form in decades. This 2021 model year sits right in the middle of that generation's run, meaning it benefits from any early production refinements while still feeling fresh and current. At just under 69,000 miles, this sedan is well within its stride — BMW's B48 turbocharged four-cylinder engine is known to comfortably reach 150,000 miles and beyond with proper maintenance. The striking Alpine White exterior gives this car a clean, classic European look that never goes out of style on San Diego streets.

2021 BMW 330i Performance and Engine

Under the hood sits BMW's 2.0-liter TwinPower Turbo four-cylinder — the B48 — producing 255 horsepower and 295 lb-ft of torque. It's paired with an 8-speed sport automatic transmission that includes both Sport and Manual shift modes, giving you real flexibility depending on whether you're cruising Pacific Coast Highway or carving canyon roads in the hills east of the city.

The rear-wheel-drive configuration keeps the 330i true to BMW's driving philosophy. This isn't just a luxury sedan — it's a driver's car. The weight distribution, steering feel, and chassis balance make it genuinely engaging in a way that many competitors simply can't match. Expect a 0-60 time of around 5.6 seconds — quick enough to feel confident in any situation on San Diego freeways or surface streets.

2021 BMW 3 Series Features and Interior

The 330i Sedan trim brings a well-appointed interior that blends sport with sophistication. BMW's iDrive infotainment system is intuitive and responsive, and by 2021 it had matured into one of the best setups in the class. Standard features on the 330i include a 10.25-inch touchscreen, Apple CarPlay, Android Auto, dual-zone automatic climate control, and a leather-wrapped multifunction steering wheel with paddle shifters.

The cabin is built around the driver, with supportive front sport seats, high-quality materials throughout, and excellent outward visibility. Rear passengers enjoy genuinely usable legroom — a meaningful improvement in the G20 generation over its predecessor. The trunk offers 17 cubic feet of cargo space, making this sedan as practical as it is fun to drive.

BMW 3 Series Reliability and Ownership

The G20 330i has earned strong marks from both automotive journalists and real-world owners. The B48 engine is one of BMW's most dependable modern powerplants, used across multiple models in the lineup. Common ownership experiences include smooth, trouble-free daily driving when maintenance intervals are respected — particularly oil changes using the correct BMW-spec synthetic oil.

At 68,697 miles, this car is past the break-in period but nowhere near the end of its useful life. Buyers who keep up with scheduled service — typically every 10,000 miles under BMW's flexible service system — routinely see these engines and drivetrains deliver exceptional longevity. It's worth having a pre-purchase inspection done, as with any used luxury vehicle, but this mileage range is considered very manageable for the platform.
