Just some rounded figures, based on those who have owned older GTRs:

Oil change $150 - $200
Every 18k miles you need
- Transmission service $1k
- Differential Fluid every 18k miles, at $50/quart
Change Rotors and Pads $8k - $10k
Replacing Transmission - $15-20k

That's obviously not a full list of maintenance. Can probably go cheaper if using Aftermarket parts, and do it outside of dealerships, if that's the risk you're ok with.
