The 2026 M3 is powered by BMW’s 3.0-litre twin‑turbo straight‑six petrol paired with an 8‑speed M Steptronic automatic on most market cars; Competition/xDrive variants exist so confirm which one you’re looking at. Running costs and servicing are higher than normal BMW 3 Series models, and optional carbon-ceramic brakes or M performance extras add significant cost but reduce fade for track use. As a brand-new car it will carry manufacturer warranty — check what BMW Ireland warranty and service plan is included with the dealer sale.

• Confirm exact specification (standard vs Competition, RWD vs xDrive, and whether carbon‑ceramic brakes or M Driver Pack are fitted) against the dealer invoice.
• Drive test to check the 8‑speed automatic shifts smoothly across modes and there’s no hesitation or flaring under throttle; verify drive modes, exhaust valve operation and launch control if fitted.
• Inspect front bumper, bonnet and lower valance for stone chips or paint defects — M cars often show tracking damage even at low age.
• If carbon‑ceramic brakes are fitted, check discs for surface cracking and that the invoice lists them (they’re very expensive to replace); if standard steel brakes, check for correct bedding and even pad wear.
• Verify all driver assistance, cameras and the infotainment/navigation functions are active and that the dealer has applied any factory software updates; confirm full manufacturer warranty paperwork is present.
