Where chaço.com is — and where it’s going
An honest look at what the tool can do today, how it works, and what we’re building next. No hype — just well-priced cars, found with numbers you can trust.
What it does today
Four marketplaces, one place
Listings from Portugal’s main used-car marketplaces — Standvirtual, OLX, Facebook Marketplace and Custo Justo — gathered and refreshed several times a day.
Every car valued
A fair-price estimate for each listing, with a confidence level and the number of comparable cars behind it — so you know which numbers to trust.
Picks & Salvage
The best opportunities ranked by trustworthy margin. Salvage (write-offs) valued against their repaired price — your upside before parts and labour.
The worksheet
Turn a candidate into a number: list the repairs, add overheads and resale, and land on a max bid you can act on.
Browse, filter, explore
The whole catalogue filterable by make, model, year, fuel, seller and more; a visual price-vs-mileage explorer; trends on which models are worth flipping; live search for a specific car.
Your pipeline
Save and stage cars from shortlist to bought/sold, see what you’ve already viewed, and an archive of listings that have gone off-market. Works on the phone, for when you’re standing next to the car.
How it works
Four steps, kept simple and explainable on purpose — you have to trust the number before risking money on it.
Collect
We continuously gather public listings from Portugal’s main car marketplaces and bring them together in one catalogue.
Value
A separate model for each make/model learns the fair price from the current market — using age, mileage, power, fuel, gearbox, trim and generation — benchmarked to dealer pricing. Every estimate carries a confidence and how many comparable cars support it.
Score
We rank how far each car sits below its fair value, weighted by confidence — a big discount on a shaky estimate never outranks a solid one. Cars priced suspiciously low get flagged to inspect (usually damage, not free money), not hidden.
Decide
The worksheet does the maths — repairs, costs, resale, max bid. We deliberately don’t auto-diagnose damage or promise returns: the tool surfaces and quantifies, you decide.
The roadmap
- Refining valuation accuracy as the catalogue and history grow
- Facebook & Custo Justo now valued against the same market, not just browsable
- Faster, gentler collection so coverage stays broad and fresh
- Deal alerts — an email the moment a new matching deal lands (stop checking, be told)
- Collection-health monitoring — so coverage never silently drops
- Post-flip learning — record what you actually bought/sold for; the model measures and improves its own accuracy
- Days-on-market — factor how fast each model sells into the ranking, not just the margin
- Compare two cars side by side; live price-drop watch on saved cars
- Smarter handling of the same car listed across several sources
- A free valuation checker — paste a listing link, get a fair-price verdict
- Possibly subscription tiers, and valuation tools for dealers
Priorities can shift — this is the direction, not a contract. The guiding principle stays the same: honest valuations you can act on.
