An online car broker predicts that one in four used cars will be bought online by 2015.
Auto Ebid says its online car sales have increased 99.6% year to date.
Such a trend may lead to a quarter of car transactions being made online by 2015, it claims.
However the company remains a tiny part of the car market. Founded in 2003, it claims to have processed 2,500 successful auctions.
The company operates a reverse auction system, which invites car dealers to bid for customers' business while the customer's details are kept secret.
