These dealers hold 'franchises' from car manufacturers to sell new cars. They're often owned by big public companies, and they're at the top of the pile. Expect smart premises, receptionists and possibly even decent coffee. This glitz is the backdrop to the shiny, seductive new motors in their showrooms.

But outside and round the back, they have big stocks of used cars. In fact, it's often their used car business that makes the real money: margins on quality used cars are better than in the cut-throat world of new car retailing.

Franchised dealers tend to specialise in used cars from the manufacturers whose franchises they hold. It makes sense: they have in-depth product knowledge, dedicated workshops and manufacturer-trained mechanics, plus a steady supply of used stock traded-in by loyal new car buyers. They're backed by manufacturers' 'approved used' car marketing schemes and advertising campaigns, and have access to stocks of ex-demonstration cars. Big dealer groups often have hundreds of cars in stock at several outlets; if a local franchised dealer hasn?t got what you want, he can probably track it down.

You'll only find the best at franchised dealers: newer cars in top retail condition, looking as good as new and backed by a generous warranty. These cars will usually have had a thorough pre-sale inspection and service - ask to see details.
