Guys, there is a reason that Ferrari is owned by Fiat; that Proton owns Lotus; that Corvette is part of GM; that Lamborghini is owned by Audi, which is owned by VW, whose shares are being acquired by Porsche; that Maserati is part of Alfa Romeo, which is owned by Fiat; that Jaguar was owned by Ford and now Tata.... ummm should I go on?
The Viper began as Dodge's kit car and had what enthusiasts wanted and we forgave them for not finishing it (like the Gen 1 "roof".) But if Viper is not economical for Cerebus to build, then the above real-world examples show a smaller stand-alone manufacturer isn't going to do any better.
Look at what it cost Stellican Ltd to resurrect the Indian Motorcycle (attempt #3 or #4, I think) and how long it took to get Chris Craft going again. The only advantage the Viper purchase has is that all the manufacturing equipment is in one place - but they still have to pay for it.
It is a little out of my league to be a marketer, but I really think this issue is the weakest link to a potential purchase. Is the new owner going to say "yes, the same engine in the Dodge Ram is in the new Chery Viper!" "You bet, the racing heritage of our new Avtovaz Viper descends from Daimler Benz!" "We put an engine in the new Kia Viper that has more torque than all our other model's lug nuts combined!"
I want to be wrong, but I think the only real hope is to find a company that is already a companion. Ilmor uses the V10 in their racing boats, so maybe somebody like them. Or think bigger and spin off Jeep and Viper together so they can share the steering column again.
One reason I've only ever owned a Dodge is that I liked the underdog position and how Dodge always had a potent 300C, Daytona, hemi, Cuda, Viper. But there's small and then there's too small.
I hope I'm wrong.
