The G20 3 Series, launched for the 2019 model year, is the 7th generation of BMW's benchmark sport sedan. Built on the CLAR platform shared with the 5 and 7 Series, it's larger, stiffer, and more technologically advanced than its F30 predecessor. While still a modern used car rather than a traditional collectible, enthusiasts are drawn to the M340i variant, which features the highly regarded B58 3.0-liter turbocharged inline-6.
The market for the G20 is active and reflects its status as a desirable late-model vehicle. With 31 sales tracked, the average price sits at $38,715, showing a typical depreciation curve from new. The price spread is wide, covering everything from early rear-wheel drive 330i models to nearly new, all-wheel drive M340i sedans loaded with options.
As these cars come off lease and enter the secondary market in greater numbers, well-maintained M340i models with desirable options like the M Sport Differential and adaptive suspension are expected to hold their value best. The 330i offers an excellent entry point, but the performance and sound of the B58 engine make the M340i the clear choice for enthusiasts looking for a future classic.
Buying Tips
- The B58 engine in the M340i is generally reliable, but check for any coolant loss, as some early models had issues with the heat management module.
- Thoroughly test the iDrive system and Digital Key functionality. Electronic glitches aren't widespread, but verifying all systems work is crucial due to their complexity.
- The M Sport Package is a must-have for many buyers on the 330i, adding better looks and suspension. For the M340i, look for cars with the Cooling and High Performance Tire Package for track use.
- Inspect the electronic service history stored in iDrive. Enthusiast owners often perform oil changes more frequently than the factory's condition-based service indicator suggests.
- Check the large 19-inch wheels, common on M Sport and M340i models, for curb rash or cracks, which can be expensive to repair or replace.
Based on 31 recent sales, prices range from $21,250 for early 330i models to $62,000 for high-spec M340i examples.
