Drive 1000 mile bringing new old car back home

A few years ago I sold my '70 Challenger 'vert to a guy in Kent, WA. This was a car that could really use a restoration but I had driven it for 4 years. He was trying to figure a way to get it transported reasonably when I told him to fly in and drive it home. He could hardly believe I thought it would make such a trip. The car didn't leak any fluids but it did use oil. I told him I wouldn't be afraid to drive it, just check the oil when he gassed up since I didn't know how much oil it would use driving steady speeds (not much, it turned out).
He flew in on a Tuesday afternoon, said he was going to take a leisurely trip back home, going north, then west. He called about noon on Friday to let me know he made it home with no problems.
Most of my old cars are driven regularly and I am pretty strict with maintenance. So I generally would have no problems taking a long trip with any of them.
As said, it depends on the car. If it's been sitting for quite awhile, I might be leery about taking the trip. If it's been driven regularly I would feel pretty comfortable starting out.
So bring a spare ballest, that way you will never need it. :thumblef:
Good luck,
