How Does Your Car's Value Change as It Gets Older?

A new car begins to lose value as it ages, but depreciation is rarely as simple as subtracting the same amount each year. Age is only one part of the equation. Kilometres driven, condition, maintenance, exact variant and market demand can all influence what a car may be worth at a particular point in its life.

The Kia Sonet is a useful example because it is available with multiple engines, transmissions and equipment levels. As a Sonet gets older, these details can become increasingly relevant when its value is assessed.

Depreciation Doesn't Follow a Straight Line

Cars generally lose value over time, but not necessarily at a uniform rate. A relatively new vehicle and an older one may experience different patterns of depreciation depending on market conditions and demand.

This means age provides useful context, but it cannot determine a used car's value on its own. Two Kia Sonet models registered in the same year could receive different valuations due to differences in usage, specifications, and condition.

Kilometres Add Another Layer

As a car gets older, its odometer usually climbs too.

Mileage can help indicate how extensively a vehicle has been used. A five-year-old Sonet with relatively low kilometres and another that has covered substantially more distance may therefore be assessed differently.

However, mileage should be viewed alongside maintenance and condition. A number on the odometer doesn't reveal everything about how the car has been looked after.

Your Exact Sonet Configuration Matters

Not every Kia Sonet starts with the same specification.

The Sonet range includes 1.2-litre petrol, 1.0-litre turbo-petrol and 1.5-litre diesel engines. Depending on the powertrain, transmission options include a 5-speed manual, 6-speed iMT, 7-speed DCT and 6-speed automatic.

Equipment also varies between variants. Higher configurations can feature a 26.03 cm touchscreen navigation system, a 26.04 cm digital cluster, ventilated front seats, a four-way powered driver's seat, and a Bose seven-speaker audio system.

Therefore, as the car ages, valuation still needs to identify the exact vehicle rather than treating every used Sonet as equivalent.

Condition Becomes Increasingly Visible with Age

Years of everyday driving naturally leave signs of use.

Paintwork can develop scratches, alloy wheels may pick up damage, upholstery can wear, and mechanical components may require replacement. The difference between normal ageing and avoidable neglect can become more noticeable as a car gets older.

Technology also needs to remain functional. The Sonet can include a 360-degree camera, Blind View Monitor, parking sensors and other electronic safety equipment on applicable variants. Higher variants can additionally feature Level 1 ADAS with 10 driver-assistance functions.

A well-functioning vehicle can therefore present differently during an inspection from one with several unresolved faults.

Maintenance History Gains Importance

Regular maintenance becomes particularly relevant as a vehicle accumulates years and kilometres.

The Sonet is supported by Kia's nationwide service network and the availability of genuine spare parts. Kia also specifies a three-year/unlimited-kilometre warranty, with an optional extended warranty of up to five years, subject to applicable conditions.

Keeping service invoices and repair records can provide useful documentation of how the vehicle has been maintained over time.

Check How Your Car's Value Is Changing

You don't necessarily need to wait until you're ready to sell to find out what your car may be worth.

ACKO Drive's free online car valuation tool lets owners obtain an estimated market value by entering vehicle details, starting with the registration number, along with information such as ownership and kilometres driven. This can be useful for checking how your Sonet's estimated value has changed as it gets older.

If you decide to proceed further, ACKO Drive also offers a free doorstep inspection. Its inspection partner conducts a 200-point assessment covering areas such as the engine, tyres, electronics and underbody. The vehicle's physical condition can then contribute to a more detailed valuation.

Market Demand Can Change Too

Your car isn't the only thing changing with time. The used-car market changes as well.

Demand for particular models, variants, engines and transmissions can evolve. New-car prices and broader used-car market conditions may also influence valuations.

This is another reason why simply applying a fixed depreciation percentage each year may not accurately reflect a particular car's value.

Final Thoughts

A Kia Sonet's value will generally change as it gets older, but age alone doesn't determine the outcome.

Mileage, variant, powertrain, maintenance, physical condition and prevailing market demand can all contribute to its valuation. Checking its estimated market value periodically can therefore provide a clearer picture of where your car stands—whether you're planning to keep it, sell it or eventually upgrade.
