The problem
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.
SlowNo structureHidden 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.
