If it’s not a classic car, you can use a signature loan to buy the vehicle, but you will pay lots more in interest, simply because a signature loan doesn’t use anything other than your signature as collateral. Therefore, paying the loan off early or more quickly is advantageous to save money.
Getting a signature loan for a car gives you a unique advantage: you have control over your car insurance. With traditional car loans, you are required to carry full coverage, but a signature loan does not have this same requirement.
