I wouldn’t say it is extremely rough! We drive it on a daily basis and rarely comment on how rough it is unless we are driving over a rough patch of road. I like the dark interior better than the light grey and personally do not like the cashmere at all. I wanted to get a white LTZ but couldn’t find one without the cashmere.Narg said:I can't stand the extremely rough riding 20" wheels. And the interior lack-of-choice killed it for us too.
GM needs to understand that the LTZ is the top of the line, and requires more choice, not less.
