BMW M42018

• **Potent performer but thirsty:** 425 bhp, sub-4-second 0–100, genuine track credentials. Fuel economy under 20 mpg combined; budget €100+ weekly fuel on Irish roads.
• **Strong residual value, premium pricing:** M4s hold well, but €54.9k is fair-market mid-range. NI import saves €2,247 before VRT—negligible after tax, registration fees apply.
• **Three serious failure modes to expect:** Carbon buildup (rough idle at 80k km), turbo wastegate rattle (under load), high-pressure fuel pump failure (€1200–€1800 repair). Any evidence of limp mode or rough running is a red flag.
• **Verify turbo condition and fuel system history before purchase:** Request specialist diagnostic on boost pressure, fuel-pump operation, and any previous carbon cleaning. Check service records for turbo seal work.
• **NI import note:** €2,247 saving evaporates after VRT (circa 20%), NOx levy, and registration—only worthwhile if sourcing a significantly cheaper example elsewhere first.
