Generally, a repo company can take your car from anywhere it's legally parked, regardless of whether it's in your county or not. They don't need your permission, and they typically won't give you advance notice. However, there might be some *limited* exceptions, such as if the repossession violates local ordinances or state laws regarding where or how repossessions can be carried out. But these are rare.
In short, while they *prefer* to repossess in your county for logistical reasons, they are not limited to doing so by law.
