 Subject: [MB] OT: Z32 300ZX turbo lifespan?
 
 Thinking of getting a '91 300ZX twin turbo.  Car is mechanically great, has 
hail damage on hood/bonnet. T tops, no leakage, oil return lines from turbos 
just replaced.  I drove it, shifts great, sounds same.  Question: When will the 
turbos go, how will I know when they're on their way out, or can they, with 
proper care and idling after a "nice" drive, last almost forever?
 Thanks,
