Buying a car together is rarely simple and can drag on quickly.
Budgets, must-haves, car links and follow-up costs are scattered across chats and spreadsheets. Without one shared basis for decisions, comparing cars gets slow; marketplaces show the purchase price, not the true monthly running costs.
Consensus before buying. A dashboard for costs.
The system finds the overlap between your budgets and feature requirements. Then you rate matching cars together; after the purchase, you can unlock car management to track every follow-up cost.
From chaos to favorite
Create a project
Give your shared car purchase a name, for example "Shared car 2026". Select important equipment such as automatic transmission, heated seats, trailer hitch, blind spot assist and cruise control. If you already completed the sharing check, we carry it over.
Invite friends
The system creates a personal invite link. Share it via WhatsApp, Signal or email and everyone lands directly in the right project.
WhatsApp
SignalBlind onboarding & reveal
Your friends do not see your preferences. They enter their budget and must-haves independently. Only then does the shared dashboard reveal the total budget and feature overlap.
Marketplace deep links
The system builds matching search links for Mobile.de and AutoScout24 using your total budget and shared must-haves. You can then import individual listings into the shortlist.
Voting & consensus
Add found cars as candidates. Everyone votes with thumbs up, thumbs down or veto. Once everyone agrees, the status changes to "Ready for viewing".

After the purchase, phase 2 starts: cost plan, AI-read receipts, fixed costs, depreciation and monthly shares stay transparent for everyone.

Frequently Asked Questions
That is exactly what you should clarify before buying: exit rules, sale, residual value, damage, repairs, unpaid costs and decision rules. wirkaufenunserauto.de helps make these points visible before a shared car turns into a conflict project.
It is most worthwhile when your usage times fit together, you have similar expectations for budget and car, and one person can take care of ongoing organization. It gets difficult when everyone needs the car at the same time, cost rules stay vague, or nobody wants to own registration, insurance and maintenance.
Not automatically. But as soon as several people contribute money and pursue a shared purpose, you should consciously clarify whether you only share costs internally, want to acquire joint ownership, or appear externally as a group. If in doubt, legal advice is sensible.
These roles are not the same. The owner is the person who economically or legally owns the car. The registered keeper is the person the car is registered to. The policyholder signs the insurance contract. Drivers are the people who are actually allowed to drive under the insurance.
Fair does not always mean 50/50. You can define purchase shares, ownership shares, fixed costs, usage costs, deductibles, reserves and depreciation separately. The important part is that everyone understands which costs are fixed and which are billed by use or responsibility.
No. The shared search, invite and decision flow are free. After buying, you can optionally use a car management subscription for ongoing costs, receipts and settlements. No subscription starts without an active decision.
