Buying the Buick 591-02136 chassis ECM (Electronic Control Module) for communication between 10-11 Saab 9-5 models involves considering its potential benefits and drawbacks. Here are some points to help you make an informed decision:

1. Cost: A new ECM can be an expensive investment, and the price might deter some buyers.

2. Installation Complexity: Installing the ECM requires advanced technical knowledge and tools. If you don't have the expertise, you may need to hire a professional mechanic, adding to the overall cost.
