One of our company's products is a valuation of used cars service. This has been enhanced today with a number plate search. Previously, users had to go through the rigmarole of choosing the make, model, engine size, mileage, number of doors, trim level, depth of tyre tread, fuel tank level and mother's maiden name (okay, I made some of those up). Now, just the number plate is required, and the correct vehicle type is summoned from dark depths of the database.
Ours is the first valuation site to offer number plate lookup, but I'm sure it will catch on. The price for a valuation remains at GBP 2.95, which includes "3 condition adjusted Trade-in values and 1 Retail value".
