Are used car warranties worthwhile? Yes, but they can vary dramatically. Manufacturer-backed warranties offer the best type of cover. This type of warranty is offered as standard among the better approved used car programmes at franchised dealers. Some cars, even in approved used schemes, are sold with dealer-backed warranties. These are often mechanical breakdown insurance policies, also known as MBI in the trade. An MBI tends to provide more limited cover than a manufacturer-backed warranty.
	You'll find that some smaller, independent traders will talk about giving you a guarantee for, say, three months, on major parts. When it comes to it, though, disreputable dealers try and wriggle out of the agreement. As with any guarantee, warranty or mechanical breakdown insurance policy, it's vital you have in writing what it covered, for how long, and what the exclusions are.
	Is it worth calling the professionals before I buy? If you need to ask the question, the answer is probably 'yes'. It's certainly the safest option, not least because you'll probably have some comeback if the professional's report turns out to be inaccurate. There are a number of specialists who will check the history of your chosen car, using data contained on computers belonging to the DVLA, the police, finance houses and insurance companies. If the car shows up on these records as being stolen, written off or the subject of outstanding finance, the specialist will tell you. You will also have a written report confirming such details as the car's vehicle identification number or VIN, colour, number plate and so on. A history check will cost about £30. There are also specialists who will conduct a full inspection of the car for bodywork, mechanical and electrical faults. Prices vary according to the complexity and size of the car, but normally start at £100. Among the specialists are breakdown companies, who usually offer discounts to members. You will receive a detailed written report on your prospective purchase and guarantees about accuracy. You may also find a friendly mechanic is willing to examine the car more cheaply. If you are sure of his or her credentials and do not want the more formal guarantees of accuracy offered by larger specialists, this can make sense. I've found the car I want, and everything checks out. Is there anything else I should do? YES! Do not hand over your cash unless you have the 'New keeper's supplement' section of the V5 (registration) document. Some sellers may offer to send off this section for you, but insist on sending it to the DVLA yourself.
