Hi, Ed.  Didn't miss the barb at all.  But since the Toyota is probably
as much domestic content as the Buick, and who knows how much of GM
common and preferred stock is actually owned by our friends overseas
(that's what happens when you have a $2 billion a day balance of trade
deficit -- they have to do something with all that money), I'm not sure
what to say, except to echo the words of Theoden King in The Two Towers
-- "How did it ever come to this?"

The first really reliable car I ever owned was a Toyota Corolla with
almost 100,000 miles on it when I bought it as a workmobile.  I more
than doubled that, and shed a silent tear when it finally retired (due
to rust from Chicago winters and street salt).  I kept the stereo on my
bench for years to remind me of what a fun little car it was.

Since you already got the plugs and wires, take a look at the
connectors on the oxygen sensors, particularly if you live in an area
where there's salt spray (like by the ocean, or where they salt the
streets in winter storms). I don't have any other additional advice,
except to try posting on alt.autos.gm and see if anyone there has
walked out this tough dog.  

Good luck
Chris
