Drive away insurance is a facility sometimes offered by car dealers to customers who buy vehicles from them. The idea is that an insurance company offers a free week's insurance policy on the car in exchange for the customer getting a quotation for a full year's insurance. We all know that it isn't really free of course - the cost of it is usually buried somewhere within the price of the car - but it can still be a very useful incentive which makes it much easier for the buyer to drive the car home immediately rather than wait until a conventional policy can be set up.
Not every dealer offers this facility of course, and those that do often reserve it for the more expensive (or more difficult to sell) vehicles and private sellers cannot offer it at all.
This is not a problem for the canny buyer. All you need to do is take along your smart phone, Kindle/iPad or even laptop when you go for your test drive and if you buy the vehicle just visit this website again and buy a policy for one, two, three or however many days you wish up to 28 days.
You can then drive the car home quite happily, and then spend whatever reasonable time you wish searching on the Internet to find a good cheap policy for the coming year. It is likely to be a lot less expensive than the policy that the 'free' drive away insurance company can offer you!
