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

suspect some other differences. Even though the use hasn't changed,

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.

If they are made the way I think they are made, it would be pretty hard
for them to be different fundamentally. I'd like to have someone who
can speak authoritatively jump in here, but I was told years ago by a GM
engineer that Chevy vs. GMC was treated just like AC vs. not AC. It is
a manufacturing option that is selected as the vehicle moves down the
assembly line.
