What would be a suitable vehicle
You may need a vehicle to make home visits to patients. This will need to be large enough to take your equipment - for example if you decide to use a portable treatment couch.
You will probably not require anything larger than a medium-sized car. Make sure that you keep the vehicle in a well-maintained and clean condition - it will help you to project a professional image.
Don't forget to tell your insurance company that the vehicle(s) will be driven for business purposes, possibly by several different drivers.
