Only 42% of those who currently own a General Motors car are even somewhat likely to buy a GM product for their next car. That figure includes just 30% who are Very Likely to do so.I don't know who would buy a GM car right now. It's somewhat ironic, since GM has steadily improved their product quality over the past 20 years. The first GM car I owned was a 1989 Chevrolet Cavalier wagon, which was underpowered, steered poorly and blew out two head gaskets. We replaced that heap with a 1997 Chevy Lumina, which I've written about at some length in the past. It was a much better car and we got 150,000 miles out of it without doing much more than routine maintenance. Some of the newer models that have been rolling off GM's assembly line in this decade have been very well regarded.
The cars that really hurt GM's (and by extension, Detroit's) reputation were the ones that they made in 1970s and 1980s, which were pretty poor. No one misses the Nova or Chevette or the Cadillac Cimmaron, to name just a few infamous examples. GM hasn't made anything that bad for years. But the damage is done.
I bought my car earlier this year and we probably won't buy another one for at least a few years. By then it wouldn't surprise me if there aren't any new GM cars left to buy.
