So here is what you might have to pay for:

T-belt - done at 70k so at 135 it's due again. It's about $900 if you have a shop do it.

CV's - The inner joints sit below the turbo heat shields and they get cooked and dry out. You will get a 50-55 mph vibration in the steering wheel if this is the case. It's $100 per side if you can do it yourself.

Cam tensioner seals - They leak, and they are at the rear of the heads and will cost you about $900 at a shop. Or about $130 for the parts and tool to DIY.

Air bags- if the car can't sit for 24 (or less of course) hours without sinking you're in it for $600 a corner to fix. Often times shady owners and mechanics will squirt tire slime into the air bags and that holds them for a few miles.

The tension leaks are a visual item, oil on the tensioner and it drips on the turbos, the rest will be vary obvious with driving and a visual inspection.

Also of note, if any of the front end is worn it's a complex multi-link system that costs about $600 in parts to replace + alignment of course.

Hope this helps.
