Trims Explained

When talking about cars, “trims” is a way of differentiating between different versions of the same model. Typically, most start with a no-frills, or “base” trim, and as features are added, or a different engine, drivetrain (gas vs. hybrid, for example) or transmission are included, trim names change and prices go up.


It’s important to carefully check the trims of the car you’re interested in to make sure that you’re getting the features you want, or that you’re not overpaying for features you don’t want.
