Choose a model year to see the list price and an indicative used-car value today. Based on official OFV list prices (2003–2008), assuming 15 000 km per year. Cars typically lose the most value in the first few years, then depreciation slows — it's not a fixed amount each year.

Questions

Frequently asked questions

How many Mazda cars are registered in Norway?
According to SSB (2025), 58,659 Mazda cars are registered in Norway (2.1% of all passenger cars). We use market data and inspection history when valuing your Mazda.
What is a Mazda RX-8 worth?
Sonja gives you a free price estimate for a Mazda RX-8 based on market data, list prices, EU-inspection history and demand. We factor in year, mileage and condition, and give you one concrete offer – fast, safe and easy.
How much does it cost to use Sonja?
Getting an offer from Sonja costs nothing: valuation, follow-up, and collection are free. We do not charge commission—we buy the car directly from you. The offer applies to the specific car you enter in the form.
How quickly will I get an offer?
You'll receive an offer quickly. After you accept, we arrange pickup and payment.
What cars does Sonja buy?
We buy most Mazda RX-8 cars when they make sense in the market. We assess year, mileage, and condition for the specific car—submit the form for a concrete offer.
What is the difference from a private sale?
A private sale means listing the car, filtering inquiries—often including low offers from dealers—and having strangers visit your home for viewings. With Sonja you get one concrete offer and one agreed pickup.
How much did the Mazda RX-8 cost new?
We show indicative list prices (new) for the Mazda RX-8 from OFV on this page. The new list price is one of several reference points Sonja uses when estimating what your used car is worth today.
Does Sonja use EU inspection data for the Mazda RX-8 in its assessment?
Yes. We use historical PKK data (periodic vehicle inspection) for the Mazda RX-8 as one of several factors in our offer. It gives us a clearer picture of the model's typical technical condition over time.
What do I need to do to sell my car?
Enter your registration number and mileage. We pull technical and ownership data from the road authority automatically and send you an offer.
