If you are looking to buy a used car, it is important that you understand your rights as a buyer, and the seller's obligations under trading standards law.
You should always make sure that you trust the seller you are buying from; you can do this by checking the reputation of the firm before you buy, or looking for sellers who are members of a trade association; this will protect you should anything go wrong.
It is also recommended to look into the condition and history of the car you are buying. Doing this will reveal if there are any potential problems, or if it has previously been sold illegally.
