Well, Dodge is bad at supporting teams. Pontiac is dead, Plymouth is dead, Oldsmobile is dead, Mercury is dead, GM and Ford do not want another brand to compete against themselves
(Which I believe is one of the reasons GM pulled Pontiac out of NASCAR)
Without Toyota it would be Ford Vs Chevy, and with the common body shapes, might as well become indycar. Toyota may not belong in NASCAR, but NASCAR is already lacking manufactures, and GM and Ford are not willing to give the support Big Yota teams get.
If I had the money to bring back Pontiac I would bring back its famous nameplates, and bring the Pontiac name back to NASCAR, replacing Toyota.
If I owned Pontiac, THIS would be my lineup
Grand Prix (The Base model, comes in coupe and sedan fourm)
G8 (High Performance Sedan, would succeed where the SS did not, Would be entered in the Cup Series)
GTO (High Performace Coupe)
Firebird (Muscle Car, equivalent to Camaro potential Xfinity Series Entry?!?)
Trans Am (Performance Trim Firebird)
G8 ST (Coupe Utility Vehicle, potential Truck Series Entry?!?)
G8 PT (High Performace Trim ST)
