Main dealer
It’s not only new cars main dealers sell, most main dealers carry a decent stock of used cars too which are normally affiliated with the manufacturer they represent. This means the sales staff there will have a good knowlede about the cars and enable you to get the right car fro you. Also, you can expect a good level of customer service, finance deals and warranties, but this service does come at a premium.
Used car dealers
Specialising in used cars, independent used car dealers are available in most cities throught the country. They usually have a smaller number of cars for sale, but from a larger variety of manufacturers. Also, you will usually pay less for a car than you would at a main dealer.
