Cross Country Traveling w/ Old Car! Tips? What should I have my mechanic check on before I leave?

And I'm gonna test drive it a little and have my wife drive the other car behind me and see if she notices parts falling off or wheels wobbling like spinning plates or anything.

I also plan on taking it in to our mechanic guy before I leave and want to know what specifically I should ask him to look at.

Any suggestions on what to check?

Also, any suggestions for taking an old, beat up car long distance?


For instance: Maybe I should only drive it for 5 hours a day MAX ....or something?
I have no idea. So any suggestions or experiences you got are great.
