Just came back from a 2 week vacation from Puerto Vallarta Mexico. I probably saw about 6 HHRs thoughout my stay. I passed by a Chevy dealership everyday and did not see a one on the lot. By far the #1 auto are Nissans and this is not even close. I know HHRs and VWs are made in Mexico and they are very loyal to thier brands. Not sure why this is (can't order them fast enough, not rugged enough for the area, etc....). Just posted this to see if anyone else has any ideas.
P.S.
Most of the roads would cut a hummers life in half!!!!

 

I lived in Mexico for three years.. Had an Isuzu Trooper. 4x4, 4cyl, 5sp. Loved it and it took all Mexico had to offer. Never a problem.
