How to Save Money on a Used Car: A Complete Guide

Buying a used car can be one of the smartest financial decisions you’ll ever make. Not only does it save you from the steep depreciation that new cars face, but it also opens up a wide range of options that fit every budget. However, the process can be tricky if you’re not careful. From understanding financing options to checking the car’s history, making the right choices is key to ensuring long-term value. For many UK buyers, platforms like Carboom are making the process of finding, comparing, and financing cars easier and more transparent than ever.

In this guide, we’ll walk you through everything you need to know about saving money on a used car—from budgeting to negotiating, financing, and maintenance tips.

1. Set a Realistic Budget

Before you even start looking at cars, it’s important to know how much you can afford. Your budget should include not only the purchase price but also insurance, road tax, MOT, and potential repairs.

• Rule of thumb: Don’t spend more than 15–20% of your annual income on a car.
• Use online calculators to estimate monthly repayments if you’re considering finance.
• Always leave room in your budget for unexpected costs such as tyre replacements or servicing.

2. Explore Different Financing Options

Not everyone can buy a car outright, and financing can be a great way to spread the cost. The UK market offers several car finance solutions, each with its pros and cons:

Financing Option	How It Works	Pros	Cons
Hire Purchase (HP)	Pay a deposit, then monthly instalments until you own the car.	Simple, fixed payments, ownership at the end.	Higher monthly costs than leasing.
Personal Contract Purchase (PCP)	Pay a deposit + monthly instalments, with the option to buy, return, or trade in at the end.	Flexibility at the end of the contract.	Mileage limits, balloon payment if buying.
Personal Loan	Borrow from a bank and pay the seller directly.	Immediate ownership, flexible terms.	May need good credit, higher interest.
Leasing (PCH)	Pay to use the car for a set time without ownership.	Lower monthly payments, always drive newer cars.	No ownership, fees for excess mileage.

Always compare APRs, total payable amounts, and contract terms before signing any agreement.

3. Research Before Buying

Knowledge is power when it comes to buying a used car. Before making any decisions:

• Check market prices: Use car valuation tools to see if the seller’s price is fair.
• Review reliability ratings: Some cars are known for durability, others for costly repairs.
• Read reviews and forums: Get insights from real drivers on running costs and common issues.

Doing your homework upfront can save you thousands in the long run.

4. Inspect the Car Thoroughly

A shiny exterior doesn’t always mean the car is in good condition. Always:

• Inspect for rust, dents, and mismatched paint.
• Check the tyres for even wear.
• Look under the bonnet for leaks and odd smells.
• Test all electronics, including lights, windows, and infotainment.
• Take it for a test drive and listen for unusual noises.

If you’re not confident in spotting issues, hire a mechanic for a pre-purchase inspection—it’s a small investment compared to the potential cost of repairs.

5. Verify the Vehicle History

One of the biggest mistakes buyers make is skipping background checks. Always:

• Get a full HPI check (to see if the car is stolen, written off, or has outstanding finance).
• Confirm the MOT history on the DVLA website.
• Match the V5C logbook details with the seller’s ID.

These steps protect you from fraud and ensure you’re making a safe purchase.

6. Negotiate the Price

Don’t be afraid to negotiate—most sellers expect it. Here are some tips:

• Research similar cars to strengthen your bargaining power.
• Highlight any issues or upcoming expenses (like new tyres).
• Be polite but firm—walking away is often your best leverage.

Even saving £500 on a deal can make a big difference in insurance, tax, and future maintenance costs.

7. Think Long-Term Costs

Buying a car is not just about the sticker price. Consider:

• Fuel efficiency: A more economical car could save hundreds yearly.
• Insurance group rating: Higher groups mean more expensive premiums.
• Servicing costs: Luxury brands often come with higher repair bills.

Sometimes, a slightly more expensive car upfront is cheaper to run in the long term.

8. Maintain Your Car Wisely

Once you’ve bought your used car, smart maintenance keeps it reliable and reduces costs:

• Follow the service schedule religiously.
• Learn to do simple tasks yourself (oil checks, topping up fluids, tyre pressure).
• Use trusted garages and compare repair quotes online.

Preventive care goes a long way in avoiding major breakdowns.
