These price quote services can help you find the best deals on new cars. Since a new car is a major purchase, it is worth it to get free price quotes from each service to find the best price on your new car. Each of the price comparison shopping sites solicits new car price quotes from different sources (usually dealers local to your area), so get price quotes from each to find the best new car deals.
Include the online dealers in your new car search, because they may undercut the best prices from the price comparison services. In addition to very low prices on new cars, the online dealers give very fast price quotes (some give an instant quote), and you never have to deal with a local dealer referred from a price search service, who will sometimes still try to haggle about the price or try to talk you into other options.
