Subaru EZ36.
Big, dumb, naturally aspirated 6 cylinder boxer that was still being made new until a few years ago. No common issues, great sound, decent torque.
I liken it to the J35 - a 25 year old design that’s stood the test of time, except this one never got the GDI and VCM treatment, thank God. I’ve owned many cars and it has always remained my favorite non-performance engine.
Not welcoming BMWs that leak oil is like excluding alcoholics from Alcoholics Anonymous
