Order the assembly rather than the photograph
Specify the chosen model, section construction, dimensions and glazing. Track configuration and supporting hardware belong in the installation discussion because a new door is not just a set of visible panels. Ask whether the existing operator can serve the proposed assembly and list any operator work separately.
Make the installation sequence explicit
Lantana lists garage doors among work requiring permits. Confirm the applicable submission, approval and inspection arrangements before setting an installation date. The written order should also explain removal of the old door, access preparation and how the opening will be managed if a delivery or onsite condition changes the plan.
Your questions
Can the old tracks always stay?
No. Tracks need to suit the new door system. Reuse should follow a compatibility assessment rather than an assumption based on similar width.
Does a new door price include a new motor?
Only if the proposal says so. Door replacement and operator replacement are separate parts of the scope even when completed together.
