I used to believe the same thing about GMC and Chevy, only cosmetic

the
GMCs require about 1/2 the maintenance as the Chevys did. Simple
things
like sticky throttles, intermittent switches, loose exhaust
brackets,
etc. don't seem to be plaguing our GMCs like they did the Chevy
variant.

My wife says they "sound" different too; "tighter and more
put-together".

Just shows you the games our mind can play one us. They are made in
the
same plant. http://www.autofieldguide.com/articles/070207.html

I believe they are actually made on the same production line, but the
same people, with just a few parts (grill, some interior parts, etc.)
being different, but I can't find any proof of that at the moment.
The
engines and components are identical so any difference you are seeing
is
a sample difference, not a Chevy vs. GMC difference.

Maybe as time goes on they are getting a little more careful and have
learned a few things. Could be the Chevys and GMCs are not completely
identical mechanically and operationally.
