If you are in the market for a new car then why not look at buying an ex demo car. Ex demo cars are often vehicles that have been registered by a main dealer either to meet a target or to be used by their sales people. The mileage on them car vary from less than 100 upwards of a few thousand. Even if the car only has a few miles on the clock it is still classed as a used car although you will not be able to see much of a difference. You will still also receive the remainder of the manufactures warranty on the vehicle, so if buying one that is only a few months old, nearly all the warranty you would get if buying brand new.
There is a massive saving to be had on buying ex demo cars and it is known that cars often lose a huge amount of their value as soon as they are registered so by buying an ex demo the car will have already depreciated by this amount.
