Short answer
Plan on a credit card. Grant Motor Group places a refundable security hold in the renter's name before you drive off, and a credit card is the best way to carry it; a debit hold ties up your own cash. Confirm with us whether a debit card can work for your booking. The hold reserves funds without spending them. Its size depends on which car you book, and staff confirm the exact figure at booking.
To rent an exotic car at Grant Motor Group, plan to bring a credit card. We take a refundable security hold in your name before you drive off, and a credit card is the best way to carry it; a debit hold ties up your own cash. Confirm with us whether a debit card can work for your booking. A security hold is a short freeze on funds, not a charge. The card must belong to you, match the name on your license and insurance, and have enough open room for the hold your car needs. This advice is standard across the exotic rental world, and the reasons behind it are practical.
The main reason is the security hold that protects a six-figure car. Every rental starts with a refundable authorization, and on a credit card that reserves part of your credit line without taking any cash. That buffer covers the risk while an expensive car is in your care. Our fleet runs from a BMW M2 Competition at $399 a day to a Ferrari 458 Italia at $1,499 a day (confirm current pricing when you book), and the cars themselves are worth far more than any daily rate. A Corvette Z06 makes 670 horsepower from a hand-built V8. A Ferrari 458 tops 202 mph and was the last naturally aspirated V8 Ferrari before the turbo era. Cars like these cost real money to repair, so the rental has to be backed by a card that can hold a meaningful sum.
Plenty of renters assume a debit card with a healthy balance is as good as a credit card. A debit hold freezes your own cash instead, so confirm card options with us when you book to keep pickup day smooth.
A credit card hold freezes money you have not spent, while a debit hold ties up real cash sitting in your checking account. That is the core difference, and it is why debit does not work well for this. On a credit card, the hold lowers your available credit for a while, then drops off. Your own money never leaves your bank. On a debit card, the bank freezes funds in your account "as a means of assuring payment to the merchant," per the Georgia Attorney General's Consumer Protection Division, which can leave you unable to spend money you actually have.
The refund path is different too. With a credit card, a hold is a pre-authorization, which means "the money is blocked but not actually taken," as the Nomora rental deposit guide explains. After you return the car clean, the hold is released, usually within a few days to two weeks depending on your bank. Debit-card and cash deposits are often taken as a real charge instead of a hold, so they take longer to come back to you. You would be waiting on a refund of your own cash rather than watching a temporary hold expire.
Timing on debit can also stretch out. The Georgia Attorney General's office notes that a hold "generally lasts for not more than a day" with the merchant, but that some card companies "allow up to three days for banks to clear transactions." The same office suggests using a credit card to reserve a car and switching to another card only for the final bill, so a large hold never locks up your checking account. That advice lines up with how we suggest you handle a rental. A credit card carries the hold. Your everyday cash stays free.
Grant Motor Group does not publish one flat hold amount, because the number varies by car and is confirmed when you book. A hold for the BMW M2 is not the same as a hold for the Ferrari 458, since the cars carry very different values. So the honest answer is a range, and then a call to confirm your exact car.
The figures below are common industry numbers converted from a euro-based guide, not Grant Motor Group's published figures. They tell you the approximate neighborhood to expect, not a quote:
| Vehicle class | Typical hold range (industry) |
|---|---|
| Economy and compact | About $150 to $400 |
| Mid-size and standard | About $300 to $700 |
| SUV and van | About $600 to $1,200 |
| Premium and luxury | About $1,000 to $3,000 or more |
Those ranges come from the Nomora deposit guide, which lists premium and luxury holds at roughly 1,000 to 3,000 euros or more and notes that "every operator sets its own" amount. Exotic supercars sit at the top of that band or above it, because the replacement cost is so high. A car like the Lamborghini Urus S makes 657 horsepower and is one of the most in-demand exotics on the road, and its hold reflects that value. The practical takeaway is simple. Make sure the credit card you bring has open room in the low thousands, then confirm the precise figure for your car with our team so there are no surprises at handoff.
One more point that saves money. A hold is refundable. It is released after a clean return inspection. The car's condition is checked at handoff and again at return. If the car comes back the way it left, the hold falls off on its own. You are not paying that amount. You are simply parking it for the length of the rental.
The card for the hold is one of a few must-haves, and they all need to point to the same person. To rent an exotic with us, you bring a valid driver's license, proof of full-coverage auto insurance that is active and in your own name, and a card (ideally a credit card) that matches. You also need to meet the age rule. The minimum age is 25, or 21 with prior approval from Grant Motor Group.
Two of these tie directly to the card. Your insurance must be in your name, and the credit card that carries the hold should be in that same name. Rentals get complicated when the driver, the insured, and the cardholder are three different people, so we keep them lined up as one renter. Your personal policy is the primary layer of coverage while you drive, and a standard policy often has value caps or vehicle-type limits, which is another reason the security hold exists as a backstop.
If you are visiting from out of state or abroad, the card advice does not change. A U.S. or international visitor should still plan on a credit card for the hold, plus a valid license (international visitors bring a valid driver's license from their home country, plus an International Driving Permit if that license is not in English). Confirm with us whether a debit card can work for your booking, no matter where you are traveling from.
Plan on a credit card in your own name, with room for a hold in the low thousands. That single card carries the refundable security hold, keeps your checking account untouched, and lets you drive off in the car you booked. If you only have a debit card, confirm with us whether it can work for your booking before you count on it. If you want to know the exact hold for a specific car, ask before you book so you can pick the card with enough room.
