Carma

Carma reads Singapore's used-car listings around the clock and gives each car a Carma score out of 100 against similar cars: depreciation (half the score), mileage per year, number of owners and COE left.

It flags price cuts and how long a car has been on the market, takes COE renewals out of asking prices so cars compare like for like, shows what a car really costs a year, and has price guides for over 500 models. Owners and dealers can list their cars on Carma too.
