Overseas Military Auto Source Car Purchase + PCS to Hawaii in 6 Months — Sales Tax/Use Tax?

Hi

Looking for some clarity from anyone with experience here:

Context:
• I plan to buy a new vehicle through Military AutoSource while still overseas.
• I would take delivery of the car overseas and drive it here until my PCS sometime early next year.
• I’ll PCS to Hawaii and bring the car with me.

My Questions:
1. When I register the vehicle in Hawaii, will I be hit with a sales tax or use tax?
2. Since the car is obtained overseas (not delivered directly to Hawaii by MAS), does that change how Hawaii views the tax?

I’ve found conflicting info online and don’t want to be surprised when I register the car. Any first hand experience or guidance would be really appreciated.
