Character

M41

"E36 318tds. Pre-common-rail indirect injection. Simple, economical. No swirl flaps, no DPF. Timing belt. Injection pump can fail at very high mileage. Cast iron block. Reliable and cheap. Low power is the only complaint."

B58

"Possibly BMWs best engine ever. Forged internals, insane tuning (600hp+). 300k+ km."
