Buyers are reminded to check out thoroughly any site that they intend to deal with. Two broad categories of site are available one that points you to a dealer and leaves you to negotiate a price and how the vehicle is to be collected. The other offers a tailormade service. It takes up to four months for a car to be delivered via an internet site. Read carefully all the details given and compare all prices with other dealers. Remember these sites may not always be the cheapest. Pay deposits by credit card and watch out for hidden extras such as road tax, delivery, registration and administration fees. Get everything in writing.
