Questions

Frequently asked questions

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 within 48 hours. After you accept, we arrange pickup and payment.
What cars does Sonja buy?
We buy most BYD Seal 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.
Does Sonja use EU inspection data for the BYD Seal in its assessment?
Yes. We use historical PKK data (periodic vehicle inspection) for the BYD Seal 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.
