About
Buying a used car means juggling a dozen listings, none of which tell you the one thing you want to know: which of these is actually worth my time?
BluishBook answers that. Add the cars you are considering and it scores every one out of 100, then puts them in order so the best buy is at the top.
It scores what actually matters
Not "which is the nicest car", but "which is the best buy". Three things decide it:
- Price against what the car is really worth
- How much usable life you get per dollar spent
- Condition and risk: title status, scam flags, known problems
That is why a cheap high-mileage car can beat a shiny expensive one, and why an overpriced car with a salvage title lands at the bottom where it belongs.
Add a listing without typing it out
Paste the text of an ad, or add screenshots of it. BluishBook reads the year, make, model, trim, price, mileage, title and location, estimates what the car is worth, and fills the form for you.
Know what it is going to cost you
Every car gets the faults its model is actually known for, at roughly the mileage it is on now, with a figure to budget. A car needing a $2,500 job soon is not the bargain its sticker suggests, and the score reflects that.
Check it before you drive out there
- Decode a VIN for the exact year, engine and trim
- Open safety recalls straight from NHTSA
- Risk flags for the things that make a listing feel wrong
