Buying a GM 1103205 Pontiac 350 400 455 vacuum advance distributor for your vehicle comes with its own set of advantages and disadvantages. Here's a breakdown of each:

1. OEM Part: This distributor is an original equipment manufacturer (OEM) part, meaning it is designed and built by the same company that originally equipped it in your vehicle. This ensures a perfect fit and compatibility with your engine.

2. Reliability: OEM parts are generally known for their reliability and durability. By choosing an OEM distributor, you can have confidence that it will perform well and last longer than aftermarket alternatives.

3. Quality: The manufacturing process and materials used to produce OEM parts are of a higher quality than aftermarket parts. This can lead to better performance and longevity.

1. Cost: OEM parts tend to be more expensive than aftermarket parts due to their higher quality and the brand name associated with them.
