Most car rental companies in Stuttgart require a credit card for renting a car. This is because the credit card is used as a form of security deposit in case of any damages or unpaid fees. If you do not have a credit card, it is best to check with the rental company if there are any alternative payment options available.

To rent a car in Stuttgart, you will typically need the following documents:

• A valid driver's license from your home country or an International Driving Permit (IDP)
• A valid passport or identification card
• A valid credit card in the name of the primary driver
• Proof of insurance coverage, if applicable

It is always recommended to check with the rental company beforehand for their specific document requirements.

The average cost of renting a car in Stuttgart can vary depending on various factors, such as the rental duration, type of car, rental company, and any additional services or insurance coverage selected. On average, you can expect to pay around €40-€80 per day for a standard car rental in Stuttgart. It is recommended to compare prices from different rental companies and book in advance to get the best rates.

While most car rental companies in Stuttgart require a credit card for renting a car, some may accept debit cards as a form of payment. However, it is important to note that using a debit card may require a larger security deposit and additional verification processes. It is best to check with the specific rental company for their payment options and requirements.

Most car rental companies in Stuttgart offer basic insurance coverage as part of the rental package. This typically includes Third Party Liability Insurance, which covers damages or injuries caused to other parties involved in an accident. However, it is important to note that this coverage may have certain limitations and exclusions.

It is recommended to review the insurance policy and consider purchasing additional coverage, such as Collision Damage Waiver (CDW) or Theft Protection (TP), to reduce your liability in case of damages or theft. These additional coverages are usually available at an extra cost.

The fuel policy for car rentals in Stuttgart can vary depending on the rental company. The most common policies include:

• Full-to-Full: You receive the car with a full tank of fuel and are required to return it with a full tank. This is the most common policy and it is recommended to keep the fuel receipt as proof.
• Pre-Purchase: You pay for a full tank of fuel in advance and can return the car with any fuel level. However, there are usually no refunds for unused fuel.
• Full-to-Empty: You receive the car with a full tank and are not required to refill it before returning. However, you will be charged for the entire tank of fuel at a possibly higher rate.

It is important to review the rental agreement and fuel policy before renting a car to avoid any additional charges or misunderstandings.
