Sorry ahead of time, I'm sure this has been discussed before, but for some damn reason nothing I search for on the search bar comes up. what are the recommended services that I need to do at 100k? More specifically, if I took the car to the dealer today, what would they do to the car that I can most likely just take care of myself?

08' G37 Coupe non-S

 

Check your owners manual for that and why would you take it to the stealership for service?

Do the work yourself or find a good local mechanic that can do all that work for you.

 

Here you go a quick 10 second Google search

DIY all day

 

As Venom said, DIY, nothing difficult. My '08 has just turned 90K and I've already done all of the recommended "severe" maintenance @80K. I'm not having any problems with the clutch, but when it hits 100K, I'm going to install the aftermarket slave, along with a new clutch, PP, and TO bearing.

 

flip open your owners manual and start reading it.

 

As far as searching is concerned, I read unless there's obvious wear or stretch, there's practically no reason to ever have to change the timing chain. True?

 

True, but if you are going to be doing other things in the timing area (tensioner, idler, and such) you might as well change all the things in there. If you have 100k miles and you are opening the front timing cover to look at wear on the chain, might as well replace it at that mileage.
