Cons:

1. Cost: The cost of a NOS M20/M18 2nd gear BW ST-10 transmission can be high, especially if it's in good condition. The cost of the transmission itself, as well as the cost of shipping and installation, can add up.

2. Complexity: Installing a used transmission in a classic car can be a complex process, especially if you're not experienced in car restoration. It may require specialized tools and knowledge.

3. Fitment: Ensuring that the transmission fits properly in your classic Corvette or Camaro can be a challenge. You may need to modify the car's engine or transmission mounts to accommodate the new transmission.

4. Availability of Spare Parts: While the ST-10 transmission is durable, it may still require occasional maintenance or repairs. Finding spare parts for this transmission can be challenging, and the cost of those parts may be high.

Buying a 1974-1981 Corvette or Camaro with a NOS M20/M18 2nd gear BW ST-10 transmission can be a worthwhile investment for classic car enthusiasts. The transmission offers improved performance, durability, and rarity, making it an attractive option for those looking to restore or upgrade their classic muscle car.
