People get freaked out about 'the turbo'...but that is kinda a 1970/80s mindset. Turbos have come a LONG way in 40 years, They arent unreliable.
Honestly, I wouldn't choose based on trying to avoid that singular failure mode. There are many many OTHER things you might contend with, a turbo failure is a very small part. And even if it were to fail, replacements are cheap. Like an AC compressor. Would you buy a car without AC to avoid AC compressor replacement?
And along those lines, driving a 6 without a turbo is like driving without AC. Maybe worse.
I just cannot recall hearing (reading) about turbo failures on these cars. FRM? Yup. JBE? Yup. lots of things may fail, but turbos are pretty low on the lost.
My 2 cents
