Is it possible to purchase a car using my American Express Platinum card?

Yes, it is possible to purchase a car using an American Express Platinum card, provided the dealership accepts American Express and the credit limit on the card is high enough to cover the cost of the vehicle. Some dealerships might be hesitant to accept credit cards for such a large transaction due to processing fees, or they may impose a limit on how much can be charged to a card. However, there are dealerships that do accept full or partial payment with a credit card. It's always wise to check with the specific car dealership beforehand to understand their policies regarding credit card payments. Additionally, one should also consider the potential impact on their credit utilization ratio and any rewards or points that could be earned by making such a substantial purchase on their American Express Platinum card.
