Car loan vs personal loan for buying a car

To buy a car, a car loan — secured by the vehicle — generally offers a lower rate, but the lender can repossess the car if you stop paying. An unsecured personal loan usually costs more, but no lien is placed on the vehicle: you own it outright from day one. The right choice depends on your credit file, the age of the vehicle and who is selling it to you.

The car loan: a loan secured by the vehicle

A car loan is a secured loan: the vehicle serves as collateral until the last payment. The lender registers a right over the car in your province’s personal property registry (the RDPRM in Quebec, an equivalent registry in other provinces). In practice, you cannot freely sell the vehicle until the loan is paid off, and the lender can take it back if you default.

In exchange for that collateral, the lender takes on less risk and generally offers a lower rate, larger amounts and longer terms than an equivalent loan without collateral.

The personal loan: more expensive, but no lien on the car

An unsecured personal loan relies solely on your credit score and your income. The money is deposited into your account, and you pay the seller like a cash buyer. The result: no registry entry, no restriction on reselling the vehicle, and no automatic seizure if you run into trouble — although a default still does serious damage to your file at Equifax and TransUnion.

The trade-off is a generally higher rate, since the lender has no asset to recover if you do not pay. The personal loan shines mainly when a car loan is hard to get: a private sale, an older vehicle, or a modest amount.

Dealer, bank or online lender?

Dealer financing is convenient: everything is settled on the spot, and manufacturers sometimes offer very low promotional rates on new vehicles. Watch out, however, for very long terms (72 or 84 months) that lower the monthly payment but increase the total cost and the risk of owing more than the vehicle is worth (“negative equity”).

Getting pre-approved by your bank, credit union or an online lender before you shop gives you a benchmark and real negotiating power: you already know what rate you qualify for and can judge the dealer’s offer on its merits.

Used cars: when the personal loan becomes attractive

The older or higher-mileage a vehicle is, the less it is worth as collateral. Many lenders raise their rate beyond a certain age (often around 8 to 10 years, depending on the lender) or simply refuse to finance the vehicle. For a used car bought from a private seller, a personal loan — or an existing line of credit — is often the simplest route: you receive the funds, you pay the seller, and the transaction stays between the two of you.

An illustrative comparison

For illustration only: on a $15,000 loan over 60 months, a car loan at an illustrative 7% would cost about $2,800 in interest, versus about $4,600 for a personal loan at 11% — a gap of roughly $1,800. Neither rate is guaranteed: the actual APR depends on the lender, your profile and the vehicle. The gap can be larger, smaller, or nonexistent.

Which loan for which buyer?

A car loan often makes sense if:

• you are buying a new or recent vehicle from a dealer or commercial seller;
• your priority is the lowest possible rate and you accept the lender’s right over the car;
• you need a larger amount or a longer term.

A personal loan often makes sense if:

• you are buying from a private seller or an older vehicle that car-loan lenders refuse;
• you want to be free to resell the vehicle at any time;
• the amount is modest and the rate gap does not justify the collateral.

Next steps

Before signing, get pre-approved for both options and compare the APR, the fees and the total cost over the full term — not just the monthly payment. Take the time to compare several lenders: for the same profile, the gap between two offers can add up to hundreds of dollars in interest. Read the entire contract, especially the seizure and prepayment clauses, before you commit.
