I was reading this and I was thinking this would be a good idea for GM to try. Performance has helped the Cadillac division, so why not try to help the Buick division. The only thing is they need to becareful about doing what they keep doing wrong in today's market. They need to seperate the Zeta's offerings. If the GNX is going to be made again it should be exactly what it was originally a turbocharged car. They should either twin-turbocharge the 3800 series III, or better yet turbocharge a V8.
I think they shouldn't offer the 6.0L in so many similar cars. The cars will begin to compete against each other instead of others. It should be limited to the Chevrolet and Pontiac division, if even the Pontiac division. If they are going to just offer the a NA V8 in a GNX, they should at least use the more technologically advanced 6.2L V8.
