I can't debate the accuracy of the study, because I don't have that information. You might well be right; the results may be dodgy. But it does start you thinking down a better route, considering the impact of the car's entire life, not just the running of it.

If it leads to just one person thinking about the issue on his own and deciding to keep his current car because the small reduction in pollution of the new model would be offset by the massive increase in pollution through manufacturing a new car to replace one that's still running fine, then it's done okay.
