Expected longevity 2008 V6 Cayenne?

[tadink]

Gents -

Looking at a 2008 Cayenne with 140k on the clock (miles).....unsure of the service history at this point but there seems to be decent documentation of service at the same shop on the carfax report.

Should I be concerned with high miles on this vehicle? If it all checks out, I already know to look at the drive shaft repair, what about the cooling tubes? Is this common to both V8 and V6 engines? What else should I pay attention to?

thanks for your help -
