Potential GM merger may hit Chrysler plants, models
A merger between GM and Chrysler is the best option under the circumstances, said Kimberly Rodriguez, principal of Grant Thornton's automotive practice.
"It's not optimal but positive in the current environment," she said.
GM has been in talks with Cerberus Capital Management since September about a merger with Chrysler LLC, the struggling U.S. automaker owned by Cerberus.
The study said Chrysler has 26 vehicle models, of which only seven were core.
The study also estimates that about $6 billion to $10 billion in costs could potentially be taken out of a merged company.
