I've bought a couple of ready twitter account for sale in the past, and it can be a mixed bag. From my experience, the pros include getting an instant audience and an established presence. If the account was active and had good engagement, it could add credibility to your brand. It also saves you the time and effort required to build a following from scratch. However, there are some cons to consider. The quality of followers might not be genuine or relevant to your niche. You could end up with a lot of inactive or fake accounts. Additionally, you might face trust issues if the followers realize the account has changed hands. There's also the risk of getting scammed if you don't buy from a reputable source.
