What really is ironic there are people shopping for a new car who had a GM before, it likely and statistically had an average or below reliability so they decide not to repair it anymore. They listen to one of those ads that educates them that their favourite make is now completely different, new and improved and above all the best to be had today. They just go and get another one, not even bothered to do a basic homework, not even a price comparison. While the above mentioned is an extreme case, GM apparently thinks very little of today's consumers who it appears they think can be so easily manipulated.
In all likeliness tomorrow somebody in their head office will wake up and take the ad down. The replacement will feature the Cruze and the latest Elantra. What we will not see is an honest comparison of either the base or top of the line models, apples to apples. But if they cannot do it for obvious reasons why make an ass out of themselves instead of just spending money on commercials and favourable media reviews?
