Our advantage
Analytics, not intuition
We collect and analyze data on every car in the Portuguese and German markets. This allows us to do what others cannot.
Real value
We know the market price of every model, year and trim — based on data from thousands of listings, not feelings.
Selling time
We know exactly how many days it takes to sell a specific model. Average times, best price, seasonality — all in numbers.
Market comparison
We compare PT vs DE prices in real time. We see where it's cheaper to buy, factoring in delivery, taxes and customs.
Fair valuation
For buyouts we name a data-backed price. We show the analytics — you see why it's that amount. No blind haggling.
