Vehicle Protection Warranty

We're a small car dealership in texas and my boss has asked me to come up with a business plan to sell warranty to customer which will take care of their car repairs in case of an accident.

We plan to charge 100 dollars/month for this service plan. I have some questions/points to make:

1.) Do we need some insurance company to back this warranty or can we back this on our own. We have a repair/body shop and we can fix the car ourselves (the parts will cost)

2.) We don't plan to take responsibility for liability, this warranty plan will cover just the repair of the car.

I'm new to all this and need help from y'all to figure out any legal requirements/implications etc.

Are we legally eligible to sell warranty or do we need some license/bond etc. Is there a price for such policy/bond.

Please help ASAP.

Does this dealership plan to get the appropriate Texas state permits/licenses to sell insurance as the primary provider?

Do you mean mechanical breakdown coverage, like a warranty? Or actual collision insurance?

This is not insurance but a protection plan that will helps us in protecting our collateral. We will not cover any liability.
Do we have to take some kind or permit/license for this? Cant we do it in house?
