Buick and Pontiac need to lose the dups.
The Torrent should never have happened. If Pontiac dealers needed a small SUV to sell, let 'em pick up a GMC franchise and sell the Torrent as a GMC.
The Montana should have been a GMC if you absolutly had to have 4 vans. I contend that you don't. The Chevy, Olds <oops Saturn>, and Buicks are more then enough.
The Pursuit should never EVER exist in the US. If you need a small car for Pontiac, base it on Kappa.
The GrandPrix needs to go. Replace the car, keep the name. The W-body line is the oldest car line GM has now that the J-body is gone.
Same goes for the LaCross. D- for effort, B+ for execution.
The person who thought the 3800 was a good base engine for the Lucerne should be told to apply to Toyota. The way that person can help GM best is by working for the competition. The 3.6VVT should have been the base, and if that wasn't possible, the new 3900.
The Rendevous is great, just don't slip behind. Upgraded engines wouldn't hurt.
The Rainier is by far the most handsome of all the TB clones. The interior could have been more unique to Buick, but the exterior is great. If you go around killing TB clones, aim for the Ascender and 9-7x.
This applies to all divisions. Quit killing off name plates that sell well. You lose brand equity that way. The Century and LeSabre were two of GM's best selling names. I can understand killing a damaged name like Vega or Citation, but LeSabre? Deville? Regal?
