What to Weigh Before Buying

Start by identifying whether rear-wheel drive or all-wheel drive better matches the intended use. The 3 Series range also spans four- and six-cylinder engines, 255–386 hp, and 0–60 mph times of 4.1–5.6 seconds, so trim selection meaningfully changes the driving character.

Fuel planning matters as well because premium unleaded is required. Compare the 26–28 city MPG and 33–35 highway MPG range with cargo needs, since the sedan provides 16.9 cubic feet behind the rear seats. Pricing should be reviewed as an MSRP reference rather than a final transaction figure.
