Now I understand what GM is doing. All these recalls are just a new method of marketing their new cars to dissatisfied customers of their old cars. And they said the bitch in charge didn't know what she was doing.But as of early July, the two dealerships run by brothers Ray and Mark Scarpelli are humming. Ray’s sales were up 13 per cent on the year and Mark’s were up 20 per cent. GM as a whole posted a 2.5 per cent increase in sales in the first half of the year, just a step behind the industry average of 4.3 per cent.
