Not Checking Your Credit Before Applying

Summary: Checking your credit score before applying for car finance helps you understand your eligibility, avoid rejection, and potentially secure lower interest rates.

Your credit score plays a pivotal role in the interest rate you’ll be offered when financing a car. Failing
to check your credit score before applying for a loan can lead to disappointment, especially if you’re
declined or given higher monthly payments than expected. Lenders use this score to evaluate your
creditworthiness, so it’s vital to ensure your credit report is accurate. If your credit score needs
improvement, consider taking steps to boost it before seeking car finance to secure more favourable
terms. We’ve outlined how your credit score affects your car finance in our blog How Does Your Credit Score Affect Your Car Finance?

Overlooking The Total Loan Amount

Summary: Focusing only on monthly payments can hide the true cost of car finance, so it’s important to consider the total loan amount, interest rate, and overall repayment.

It’s easy to get fixated on low monthly payments when shopping for a car loan, but this can be a
mistake. A longer loan term might offer lower monthly payments but can end up costing you more in
interest over the life of the loan. Instead of solely focusing on monthly costs, consider the total loan
amount and the interest rate to gauge the actual cost of your car purchase. This will help you make a
more informed decision.

Ignoring Loan Duration And Terms

Summary: Choosing a longer loan term can reduce monthly payments but often increases the total interest paid over the life of the car finance agreement.

Extending your car loan to a longer-term might seem like a great way to reduce monthly payments,
but it can lead to higher overall costs. Longer loan terms often come with higher interest rates, and
you’ll be paying interest for an extended period. Be sure to understand the loan terms and choose a
duration that aligns with your budget and financial goals.

Top Tip: Take into consideration the age of the vehicle you’re looking to finance, if you take a longer
loan term, will you still want to drive that vehicle 5 or 6 years down the line? The answer might still
be yes, as many vehicles are still reliable at 12 to 15 years old.

Skipping The Fine Print: Hidden Fees And Penalties

Summary: Reading the finance agreement carefully helps you identify hidden fees, penalties, and conditions that could increase the total cost of your car loan.

Don’t rush through the loan agreement without carefully reviewing the fine print. Some lenders may include hidden fees or penalties that can catch you off guard. Look out for prepayment penalties, late
fees, and any other charges that could add to the cost of your loan. Different loan types have different fees attached to them, for example, a PCP agreement includes a balloon payment at the end of your finance agreement if you choose to keep your vehicle, so it’s worth making sure that you’re able to afford this final payment.

PCP agreements may also include mileage limits, which can lead to excess mileage charges when returning the vehicle.

Falling For Too-Good-To-Be-True Deals

Summary: Some dealership finance offers advertise very low monthly payments or zero deposit deals but may include higher interest rates, longer terms, or hidden costs.

Some dealerships advertise extremely low monthly payments, zero deposit offers or limited-time finance deals. However, these offers may include longer loan terms, higher APR rates or hidden fees. Be cautious of offers that promise no down payment, zero interest, or exceptionally low monthly payments. Often, these deals come with strings attached, such as high-interest rates or hidden fees. Do your due diligence and research the offer thoroughly before committing. Researching the lender through online reviews are a great way to understand the dealership’s legitimacy, so read through their past and current customers are saying before signing anything.

Not Shopping Around For Better Rates

Summary: Comparing finance offers from multiple lenders can help you find lower interest rates and better terms for your car finance agreement.

Don’t settle for the first finance offer you receive. Shop around and compare rates and terms from multiple lenders, including banks, credit unions, and online lenders like Marsh Finance. By doing so, you increase your chances of finding a loan that suits your financial situation and offers the most competitive terms. Many lenders offer soft searches, which gives you an idea of what your loan would look like without affecting your credit score, a big bonus if you’re shopping around.

Overextending Your Budget

Summary: Borrowing more than you can comfortably afford can lead to financial strain, so it’s important to choose a car finance deal that fits within your realistic budget.

Finally, avoid overextending your budget to buy a car that’s beyond your means, car FOMO can lead to financial stress and difficulties down the line. Stick to a budget that aligns with your income and
expenses to ensure a smooth car finance experience. While lenders should evaluate your affordability, the loan may still be stretching your own personal budget. There are plenty of great cars that fit any budget, so do your research to find your dream car that is still affordable to you.

Avoid Ignoring The True Cost Of Owning A Car

Summary: The real cost of owning a car includes fuel, insurance, road tax, servicing, maintenance and depreciation, not just the monthly finance payment.

The cost of a car isn’t just the sale price, it incorporates fuel costs, road tax, maintenance and many other factors that need to be considered when purchasing a car. Avoid purchasing a car that’s right at the top of your budget, as you may not be able to afford it once other payments have been taken into account. Here are some of the common additional costs to owning a car, as well as the expected costs in the UK:

⛽ Fuel - £747 to £1,300 (depending on fuel type)

🔧 Maintenance - £473

📃 Insurance - £737

🚖 Road Tax - £195

📉 Depreciation - £1,251

Total cost of running a car in 2025: £3,403 to £3956

Not Getting Pre-Approved For Car Finance

Summary: Getting pre-approved for car finance before visiting a dealership helps you understand your borrowing power, compare interest rates and avoid accepting unfavourable finance terms.

Getting pre-approved for finance before you visit a dealership can help you compare different options and find something that suits you. Pre-approvals at Marsh Finance don’t affect your credit score, allowing you to check your eligibility before you shop.

Not Understanding Vehicle Depreciation

Summary: Vehicle depreciation affects how quickly a car loses value, and choosing a model with strong resale value can help reduce the risk of negative equity during a finance agreement.

Some cars lose value quicker than others, affecting your resale options down the line. Failing to check this before financing can leave you struggling to shift your car down the line. Pick a car that holds its value well over time to guard against any issues.
