Used 2021 Bmw X3 M40i

Since you are looking at a 2021 model, here are a few specific things to keep in mind for this particular year. The Engine: The 2021 M40i features the B58 engine paired with a 48V mild-hybrid system. This setup provides smooth auto start-stop transitions and an extra boost of torque for better efficiency and punchy acceleration. Tech Standards: By 2021, Android Auto and Apple CarPlay were standard and wireless, which is a major convenience over older models. iDrive 7: This model year uses one of BMW's most stable and user-friendly infotainment systems, featuring a mix of physical buttons and a responsive touchscreen. Things to Verify Before Buying: Service History: Since the listing mentions it is "well-cared for," ask for the BMW service records. This engine is very reliable, but regular oil changes are critical for the turbocharger's longevity. Tire Condition: The M40i often comes with staggered performance tires. These cannot be rotated front-to-back and tend to wear faster than standard tires; check the tread depth to ensure you won't need an immediate $1,200+ replacement. Brakes: The M Sport brakes on this trim provide excellent stopping power but can be expensive to replace. Check if the pads and rotors have plenty of life left. Comparison Tip: If you are comparing this to other SUVs, the X3 M40i generally holds its value better than the base 30i model because of its desirability among enthusiasts.
