My recent experience was HORRIBLE ! You keeping my vehicle for a week for an hour repair really makes the GMC experience just like owning a FORD! the new policy changes for service are You keeping my vehicle for a week for an hour repair really makes the GMC experience just like owning a FORD! the new policy changes for service are TERRIBLE !
