"Today's tech-savvy consumers shop for their vehicles online in an attempt to bypass the traditional buying process. Yet, to date, most online 'auto buying' services use the Internet merely to gather and resell customer information to dealers, essentially dumping consumers back into the traditional model they sought to avoid by shopping on the Internet." - Rodney J. Couts, Executive Director of the Internet Auto Dealers Marketing Association.
Most locating services charge dealers for leads and rarely save consumers any money, though they may be some-what convenient.
