### Cons of Buying a 91154 Window Crank Handle
1. **Limited Availability**
Authentic or high-quality reproduction parts for older GM vehicles can be difficult to source, especially if the part is no longer in production. This may require searching through specialty suppliers, eBay, or salvage yards, which can be time-consuming.
2. **Higher Cost Compared to Modern Alternatives**
Original or reproduction riveted crank handles are often more expensive than modern plastic or stamped metal replacements. For budget-conscious buyers, this can be a significant drawback, especially if multiple parts need replacement.

Older metal parts, even if well-preserved, may still exhibit signs of rust or corrosion, particularly if the vehicle has been exposed to harsh weather or poor storage conditions. This could require additional cleaning or treatment before installation.

Metal crank handles are heavier than plastic alternatives, which may make window operation slightly more effort-intensive, especially for older drivers or those with limited strength. The design may also feel less ergonomic compared to modern contoured handles.
5. **Compatibility Issues with Modern Modifications**
If the vehicle has undergone significant modifications such as upgraded window regulators or custom window frames the 91154 crank handle might not align perfectly. This could require additional adjustments or the purchase of an adapter, adding complexity to the installation.
6. **Maintenance Requirements**
Metal parts, while durable, may require periodic lubrication or rust prevention treatments to maintain optimal function. Neglecting maintenance could lead to stiffness or binding over time.
7. **Potential for Counterfeit or Low-Quality Reproductions**
The aftermarket for classic car parts can be flooded with low-quality or counterfeit items. Buyers must carefully research suppliers to ensure they are purchasing a genuine or well-made reproduction to avoid poor performance or premature failure.
