To get Ertl quality models a buy in of 9000 MINIMUM would be needed to offer MN12 Birds (V8 and SC) at about $30 each. It seems that generating that much interest is difficult as it is, therefore a cougar model would prove to be even more difficult to attain interest.
I did however talk to GMP who make THE BEST detail models fo GTO's, Torino's, Mustangs, and Grand Nationals to name a few. These models have details beyond Ertl to include working suspensions, raising/lowering antenna & windows!! While the initial number of buy in is down to about 4000, the price skyrockets to close to $100.
Unfortunately there just isn't enough interst.
