Well we got the new ignition wires, plugs, distributor and rotor installed yesterday (Sorry Gayle it was a day yesterday). The old plugs didn't look all that bad, but they did have 39,000 miles on them. I saw some improvement in gas mileage. I hadn't reset the 2nd mileage reading in a long time and lately it had dropped a few tenths over the last couple months. Over the drive home those tenths were restored.

I probably could have gone a lot longer, without doing this, but I'm glad I did.
