The business problem

Inventory, customer interest, and staff action had to operate as one system.

604 Sell Cars brings inventory from participating dealerships and private sellers into one searchable marketplace. The challenge extends beyond displaying cars: availability changes, buyers need clear context, requests need an owner, and staff need tools that do not expose private operational data.
