Lucky,
Please take the notes about credit cards, cell phones and road service seriously. While it may have few miles, years can hurt a lot - too.
You might make 500 miles, but you should still plan on:
Tires, At least read the dates,
Belts, If you can't find at receipt that they are less than
Hoses - Fuel, Coolant and Brake
The fuel lines will have to be replaced with ethanol tolerant.
The coolant lines may be soft and weeping.
The rubber brake may have visible cracks
And the cooling system and brakes should be flushed as the contained fluid has aged out.
If any of this can wait until you get home, I wish you a boring trip.
Matt
