Why sell with Sonja?

  • No warranty liability

    When you sell privately, you are liable for defects for 2 years. When we buy your car, we take over all responsibility from day one.

  • We come to you

    No need to drive anywhere. We collect the car at your location, free of charge.

  • Less stress than selling privately

    Many people find private sales draining: lots of messages to answer, haggling and low dealer offers—and several rounds of strangers wanting to visit your home to view and test drive the car. With Sonja you get one clear offer and one agreed pickup when you are ready.

  • Transparent pricing

    Our offer is based on public vehicle data and current market prices. We explain how we arrive at the number.

  • The car is yours until you decide

    The car stays with you until you accept the offer. No pressure, no commitment.

How it works

How we make it possible

Private sales can fetch a slightly higher headline price—but many people find them draining: lots of messages, haggling, strangers at your home for viewings and test drives, plus paperwork and consumer liability. Sonja buys your car directly and runs collection, inspection, prep, and resale in one professional flow—that is where we scale. Our offer may sit a little below a theoretical top private price; you trade that for certainty, less work, and none of the usual hassle.

Questions

Frequently asked questions

Is it free?
Yes, it is completely free to use Sonja. Getting an offer costs nothing, and we charge no fees or commission from you as the seller.
How does Sonja make money?
We buy your car at a fair price and resell it through our professional network. Because we have streamlined the entire process – from collection and inspection to preparation and sale – we can do this profitably. You skip the typical private-sale grind of many inquiries and strangers visiting for viewings and test drives; we take a modest margin.
Will I get the same price as a private sale?
Our offer may be slightly below the maximum you could achieve privately. A private sale still means you handle everything: many inquiries to answer and sort, often low offers from dealers who want the car cheap, haggling—and often several strangers who want to visit your home to view and test drive the car. You also carry 2 years of warranty liability. That is stressful and time-consuming even if the car is not listed for months. Most sellers find the safety and one simple process well worth it.
How does the price estimate work?
You receive a free, automatic first estimate from current market data and your vehicle details — nothing you have to wait for us to process manually before you see it. We combine sources such as road-authority data with market signals. The estimate is indicative; the final purchase price is agreed after a closer review.
What happens after I submit?
Our system builds a free, automatic estimate from market data. If you want to proceed, we contact you within 48 hours to discuss condition and details and give you a concrete purchase offer. If you accept, we collect the car, handle paperwork and resale — and pay you out. No obligations along the way.
What if I disagree with the pricing?
The estimate is just a starting point. If you believe your car is worth more, let us know – we will review the documentation and condition and adjust our assessment accordingly.
Am I liable for defects after the sale?
No. We are the professional buyer and take full responsibility for any faults and defects once the transaction is complete. You have nothing to worry about.
Which cars do you buy?
We are interested in most passenger cars in reasonable condition. Feel free to get in touch even if you are unsure – we will help you assess whether the car suits us.
How long does the process take?
From submission to hearing from us typically takes within 48 hours. The transaction itself can be completed within a few days if you accept the offer.
