Featuring its own unique model branding, the trim levels of the BMW 3 Series draw attention of their own. The 2021 BMW 3 Series 300i has a prestigious ring to its name, one that does not go unnoticed. As the base model for the 2021 BMW 3 Series, the 300i sets expectations high for trim levels to come.

This is a desirable feature for many consumers who yearn for the affordability of a BMW that is accompanied by a plethora of possible upgrades.
