can you buy a car with amex platinum

[AylaLee]

Yes, you can typically use an American Express Platinum card to buy a car, but it's not a straightforward process and comes with significant limitations. The primary hurdle is the dealership's point-of-sale (POS) system, which often has a transaction limit far below the cost of a vehicle. While Amex itself doesn't cap the amount, most dealerships impose a cap—often between $3,000 and $5,000—to avoid high credit card processing fees. Therefore, you can likely use the card for a down payment or a partial payment, but financing the entire purchase is uncommon.

The major incentive for using the Amex Platinum is earning Membership Rewards® points. Paying even $5,000 towards a car would net you a substantial number of points. However, you must weigh this against the dealer's potential reaction. Many will add a surcharge (typically 2-3%) to cover the processing fee they incur, which could negate the value of the points earned. It's crucial to negotiate this upfront; some dealers may waive the fee for a down payment if you're also financing through them.

The process requires clear communication. You must inform the sales and finance managers of your intent before finalizing the numbers. Be prepared with a backup payment method. For most, the best strategy is to use the card for a portion of the cost to earn points, then use a certified check or financing for the remainder.

You can, but don't plan on putting the whole thing on the card. Dealers hate eating the credit card fees on a big sale. Your best bet is to negotiate the final price first, then spring it on them that you want to put, say, five grand on your Amex for the points. Sometimes they'll swallow the fee if you're financing the rest with them. Just be ready for them to say no or add a 3% charge. Always have a cashier's check as a backup.

Technically, yes, the card can be used. However, the feasibility depends entirely on the dealership's specific policies. The main attraction is accruing Membership Rewards points on a major expense. I'd recommend contacting the finance manager at your chosen dealership before you even start negotiating the car's price. Inquire about their maximum credit card payment allowance and whether a surcharge applies. This pre-approval prevents any last-minute surprises at the signing table.
