Douglas,
Currently that's what we are doing.  He got it back together as I was leaving.  He said he fired it up, and took for a test drive, no CIL, ran fine.  But this is something I've been afraid of 
with the cars going 100Kmi / plug change.  We really don't know how many miles are on these plugs as he's the 3rd owner.  I was figuring that if he was going to be in there, why not changed the plugs.  But when we ran into this problem he and I agreed, "if it aint broke, don't fix it".
But I've got an 06 Scion xB with 64K mi, and a 12 second gen xB with 74Kmi and neither has had the plugs changed.  So I'm worried I may have the same problem.
If we decide to get the plugs out in the near future, I'll keep you posted, but don't hold your breath. 

Thanks to all that responded.
