What Affects a Car's Value? 9 Factors That Decide the Price

    Written and reviewed by Arman Pargar, founder of Min Bilvärdering · Updated July 7, 2026 · 7 min read

    Two seemingly identical cars can be valued thousands of kronor apart. The reason is that a car's value is not decided by a single thing, but by how a number of factors weigh up against what the market wants right now. Here we go through the nine most important, and point out which ones you can influence before you sell.

    1. Mileage

    The number of miles driven is often the first thing a buyer looks at. (In Sweden, mileage is given in mil, where 1 mil = 10 km.) Low mileage signals less wear and a longer remaining life. As a rule of thumb, a Swedish car is driven around 1,500 to 2,000 mil per year; if your car is clearly below that, it is a definite plus in the valuation.

    2. Condition and service history

    A complete service book and receipts for work carried out raise the value more than many people think, because they remove the buyer's uncertainty. Scratches, stone chips, worn tyres and small dents, on the other hand, pull the price down, partly because the dealer factors in what it costs to fix them before reselling.

    3. Make and model

    Some makes hold their value better thanks to a reputation for reliability and strong demand on the used market. Popular models with good second-hand value sell faster and at higher prices than niche models with a thin pool of buyers.

    4. Model year and equipment

    Newer cars are generally worth more, but the level of equipment can weigh heavily. Sought-after equipment such as a tow bar, engine heater, navigation, driver-assistance systems and winter wheels can lift the price, while a stripped-down base model is valued lower even in the same model year.

    5. Fuel type and drivetrain

    Demand for petrol, diesel, hybrid and electric shifts over time and affects value. All-wheel drive is often a plus in northern Sweden. Keep an eye on how your particular combination is in demand where you live, because regional differences are real.

    6. Colour

    Neutral colours such as black, white, grey and silver have the widest pool of buyers and sell most easily. Unusual colours can appeal to some people but narrow the market, which sometimes shows up in the price.

    7. Number of owners and origin

    Few previous owners and a car that has been privately owned (rather than hard-driven as a company car) inspire confidence. Imported cars can be valued somewhat lower if the history is harder to verify.

    8. Inspection and any remarks

    A recently passed inspection (besiktning) with no remarks makes the car easier to sell. Upcoming or known faults, such as a failing timing chain or rust damage, affect the bid because the buyer factors in the repair.

    9. Demand and season

    The market moves with the seasons. Convertibles and sports cars sell best in spring, while all-wheel-drive estates and SUVs do best ahead of winter. Selling when demand for your type of car is high can bring in several thousand kronor more.

    What can you actually influence?

    • Clean and tidy the car thoroughly: a well-kept car is perceived as better maintained.
    • Gather the service book, receipts and both sets of keys.
    • Fix small, cheap faults (bulbs, wiper blades) that would otherwise give a sloppy impression.
    • Sell in the right season if you can wait.
    • Collect several bids so you see the car's actual market value instead of guessing.

    Frequently asked questions

    What lowers a car's value the most?

    High mileage, neglected servicing, visible damage and known faults that need repair. A missing service history creates uncertainty that often shows up in the bid.

    Is it worth repairing the car before selling it?

    Small, cheap fixes such as cleaning and replacing bulbs almost always pay off. Expensive repairs rarely do. It is often better to sell the car as it is and let the dealer factor in the repair.

    How do I find out what my car is worth?

    The fastest way is to request bids from several car dealers. It is free, takes all the factors above into account and gives you an actual market price instead of a guess.
