What is Car Depreciation?
Car depreciation is the difference between what you pay when purchasing a vehicle and what it’s worth when you decide to sell it. Over time, every car depreciates, but the rate at which this happens varies depending on several factors such as mileage, age, and demand.
How Quickly Do Cars Depreciate?
On average, new cars can lose 15-35% of their value in the first year, with up to 60-70% depreciation within five years. However, the first three years tend to see the most significant decline. After about 8-10 years, the car’s value may stabilise, or in rare cases, slightly increase if it becomes a sought-after model.
Key Factors Influencing Depreciation:
- Mileage: High mileage accelerates depreciation, as a higher number of miles indicates more wear and tear.
- Brand & Model: Luxury and high-demand brands often retain value better than lesser-known or unreliable models.
- Service History: Keeping a full-service history and maintaining the vehicle properly can reduce depreciation rates.
- Fuel Type: As we approach the UK's 2035 electric vehicle deadline, petrol and diesel vehicles, particularly non-ULEZ-compliant ones, are depreciating faster. In contrast, ULEZ-compliant cars tend to hold their value longer.
- Condition: The overall condition of the car, including appearance and mechanical soundness, plays a crucial role in how quickly it depreciates.
ULEZ and Clean Air Zones: A Depreciation Driver
In areas such as London, Birmingham, and Bristol, where ULEZ (Ultra Low Emission Zones) and Clean Air Zones are enforced, non-compliant vehicles (those not meeting Euro 6 for diesel or Euro 4 for petrol) are losing value rapidly. If you own an older vehicle that doesn’t meet these standards, you may want to consider selling sooner rather than later.
How to Slow Down Depreciation:
While all cars depreciate, there are ways to mitigate the rate:
- Keep Your Mileage Down: The fewer miles on your car, the slower the depreciation.
- Maintain Regular Servicing: Adhere to the manufacturer’s service schedule and retain service records to maximise your car's resale value.
- Opt for ULEZ-Compliant Vehicles: Particularly important if you drive in or around clean air zones. At Surrey Hills Motor Company, we specialise in ULEZ-compliant vehicles that can help protect your investment.
- Avoid Modifications: Cars with aftermarket modifications may not appeal to all buyers, potentially lowering their resale value.
- Keep Your Vehicle Clean: Maintaining both the interior and exterior condition of your car will help retain value.
The Future of Petrol and Diesel Vehicles
As the UK moves towards a 2035 ban on new petrol and diesel cars, older fossil fuel vehicles are seeing accelerated depreciation. However, vehicles that are ULEZ-compliant or highly fuel-efficient are still in demand and may hold their value better in the coming years.
