Never driven a BMW car but, back when I was a biker, I LOVED my BMW R1100S. Best bike I ever rode: shaft drive which made it much more resilient to UK weather, salted roads etc and, despite being a sports bike, it had plenty of room for taller people like me in a comfortable riding position (compared to the Suzuki Bandit I used to ride - urggghh). Oh and the flat twin engine was so nice: so torquey you could imagine Basil Fawlty opening a hotel there (sorry).
Anyway, yeah, BMW bikes >>>>> all other bikes. No idea about their cars. Don’t really care about cars.
