Are turbocharged petrol engines reliable?

Our car is a BMW 120i coupe "non-turbo". The latest 218 etc has twin turbos. In view of all the warnings you have issued over the years regarding turbo bearing failure doe to overheating, would we be storing up double trouble for ourselves? We are OAPs covering about 5000 miles per year.

Not twin turbos; twin spool turbo. The big advantage of turbo petrols in the winter is they heat up much faster than non turbos. Most petrol engines are now smaller capacity and turbocharged.
