A new test drive service is being launched to help drivers choose their next new car more efficiently. Trying a new car before buying it is so vital it gets an importance rating of 8.3 out of 10 from buyers according to research by company Testdrives2u. But other surveys show that as many as one in 10 don’t bother with test drives. With car buyers increasingly pushed for time, the new service could revolutionise buying a car.
