Which interior cleaning plan has a monthly rate of $44.99 for both car and SUV?

The Unlimited Super Interior Plan is the correct choice because it specifically offers a comprehensive range of interior cleaning services suitable for both cars and SUVs at a monthly rate of $44.99. This plan is designed for customers who require ongoing maintenance of their vehicle's interior, ensuring that upholstery, carpets, and various surfaces are kept clean and refreshed on a regular basis.

In contrast, the other options may not provide the same level of service or could be priced differently. For example, the Unlimited Basic Interior Plan typically includes more limited cleaning services, which might not meet all interior cleaning needs. The Unlimited Deluxe Interior Plan often includes additional premium services or features that could lead to a higher monthly cost. Basic Interior Cleaning, while likely a cost-effective option, does not represent the unlimited service model associated with a monthly subscription. Thus, the Unlimited Super Interior Plan stands out as the best choice for its value and comprehensive service offering.
