BMW M2 F87 buying guide

The compact M car, built from 2016 to 2021 as a rear-wheel-drive coupé with a limited-slip differential. The original M2 used a single-turbo N55 six; the 2018 M2 Competition and the 2020 M2 CS switched to the twin-turbo S55 from the M3 and M4.

The versions

  • M2 (2016 to 2018): 3.0 single-turbo straight six (N55), 370PS
  • M2 Competition (from August 2018): 3.0 twin-turbo straight six (S55), 410PS
  • M2 CS (2020): S55, 450PS
  • 6-speed manual or 7-speed M DCT dual-clutch, the DCT the more common
  • Coupé only, rear-wheel drive, with a limited-slip differential

What to check on a F87 M2

3 model-specific things to look at when you view one. They're a starting point, not the full inspection.

  1. Differential seal leaks

    What to look for: From underneath with a torch, look at the rear differential, particularly where the propshaft enters it at the front, and at the sensor on the casing. Dry is good; fresh oil or a wet, dirty film is the thing to note.

    Why it matters: Leaks from the differential's input seal and sensor are a known issue on the M2. They're a manageable repair if caught early, but low oil in a limited-slip differential isn't something to leave.

  2. Radiators behind the front bumper

    What to look for: Shine a torch through the lower openings in the front bumper at the radiators and coolers behind them. Look for punctures, bent fins or coolant staining, and check the plastic wheel arch liners are secure.

    Why it matters: The front coolant radiators can be punctured by the plastic wheel arch liners. A damaged radiator leaks coolant, so it's worth spotting before it turns into an overheating problem.

  3. The crankshaft hub

    What to look for: Ask whether the car has been tuned, and whether the crank hub has been upgraded or the engine re-timed. Look for invoices. On the drive, note any rough running or engine warning after hard use.

    Why it matters: A spun crankshaft hub, where the hub slips on the crank and upsets the engine timing, affects some N55 and S55 engines and is more likely on tuned cars. At best it means re-timing the engine; at worst the valves can hit the pistons. A standard car with a known history, or one with an upgraded hub, is the one to look for.
