The G42 is the second-gen M240i, new platform with more power, more tech, and a larger footprint.
Each part is scored from 0 to 100 on a fixed outside scale. Acclaim comes from published expert lists, launch reviews and awards; the more acclaimed a car, the less its ownership cost counts in this all-time score (its dollars below are unchanged). A part marked not measured carries no weight for this car, and the others share its weight.
No permitted price yet: we have not found three prices for this car from sources that allow this use.
Long-term value starts to count in the score once 75% of the 69 generations have permitted prices. Today 43 do.
About $2,103 a year to own ($1,472 to $3,263), about $9,231 over five years, bought at five years old or its own age if older, kept five years.
Expect about $1,500 to $3,300 a year; the bills that decide it are oil filter housing and valve cover gasket leaks, high pressure fuel pump and coolant loss / expansion tank. Ownership risk: moderate.

2024The best year to buy, reading 75 of 100, about $2,103 a year to own.
From our log of the changes between model years, each with its source. Only changes the score reads count as reasons; recalls BMW fixes for free, options and tuning notes do not. The cost a year is for a car bought at five years old, or its own age if older, kept five years. How the score works.
It launched in the US as xDrive only, and a rear-drive version joined for the 2023 model year, both with the 8-speed automatic and no manual. Quick and modern but less enthusiast pull than the F22 manual. For 2027 it gets the updated six with port injection and a 48-volt mild hybrid.
What goes wrong on this generation, roughly what a fix costs at an independent shop, and how to spot it before you buy. Every M240i generation compared.
Look for oil or coolant residue at the oil filter housing and the valve cover, and ask about coolant top-ups.
Ask about tune history and fueling upgrades, listen for HPFP whine at idle.
Ask whether walnut blasting has been done, budget for it on higher mileage cars.
Pre-purchase scan for PCV and misfire codes, check idle quality.
NHTSA files some owner complaints about this car under the 2 Series, so they are missing here. Read them by year, make and model at nhtsa.gov/recalls.
The low temperature cooling system, expansion tank, and water pump are the typical B58 weak spots. Loss can be slow.
Inspect the expansion tank seams, ask owner about coolant top-ups.
The plastic oil filter housing and its gaskets can leak oil or coolant, often from about 60,000 miles, and the valve cover gasket can weep. A proposed class action filed in January 2026 covers 2014 to 2021 BMWs with this engine family; BMW has moved to dismiss it, and no class has been certified. Both jobs take many hours of labor.
Look for oil or coolant residue at the oil filter housing and the valve cover, and ask about coolant top-ups.
The crankcase ventilation (PCV) valve's diaphragm in the valve cover can split, as on the earlier B58, whose valve BMW covers for 15 years or 150,000 miles; no BMW bulletin covers this engine version. Signs are rough idle, a whistle at idle and stored codes.
Pre-purchase scan for PCV and misfire codes, check idle quality.
Intake valve carbon deposits build up over time on the direct injection engine and are removed by walnut blasting; one repair shop that sells the service says cleaning is typically needed every 50,000 to 70,000 miles, and BMW schedules no such service. The 2027 engine adds port injection, which keeps the valves clean.
Ask whether walnut blasting has been done, budget for it on higher mileage cars.
The engine-driven high pressure fuel pump and the injectors it feeds can wear, bringing poor running and fuel pressure fault codes. A parts seller says the pumps and injectors on the updated version of this engine, in 2022 to 2026 cars, no longer fail regularly, but that owners will in time replace both; it gives no mileage or rate, no source we read covers the 2027 revision yet, and BMW has issued no bulletin on pump wear.
Ask about tune history and fueling upgrades, listen for HPFP whine at idle.

Our estimates at an independent shop, parts and labor; fuel from the EPA.
Pricing tires for this car? Compare the factory sizes at Discount Tire, and ask a local shop to match it.
Fuel from EPA fueleconomy.gov: its yearly cost is for 15,000 miles with 55% city driving, moved here to the miles a year the two-year budget uses. The rest are our estimates at independent-shop and retail prices from September 2026. Service is a year of routine maintenance at 10,000 miles: one or two oil changes, brake fluid, filters, and spark plugs spread over their interval. Repairs are separate. Tires are a mounted set of summer tires; brakes are pads and rotors on both axles. Prices vary by region and shop.
