My bro is looking at an older cayenne turbo s to replace his expedition EL. Being an older rig, and paying a lot of money for it, are these turbo rigs money pits if something goes wrong?
Lots of reading on the internet on this. Lots of Turbos out there running over 200-300K miles. Most of the ones in the 100K mile range have been pretty reliable. There are a few common known issues, most of those are normal maintenance type things the others are usually "one and done" updates.
I've had my 04 Turbo for 7 years. It has 133K on it and I've put roughly $2500 into it, and that includes the tune and some upgrade parts.
