The digital version offers more than 33,000 values, unlimited VRM lookups and an RSS feed streaming live industry news, in comparison to Glass’s printed car Guide, which provides around 13,000 valuations every month.

Accessible on Apple and Android smartphones and tablets, the digital Guide works online and offline, so as long as the App has been updated once a month.

Ian Tilbrook, Glass’s managing director, said: ‘The world is going digital, and having fast access to useable information is vital to dealers. We know people love the printed book, and we are confident they will love the digital Guide even more. By giving the industry greater market intelligence through more data, more content and more support, we can enable dealers to really power ahead of their competition.’

Richard Parkin, head of valuations and analysis at Glass’s, added: ‘Going digital isn’t just about technology. Glass’s as a business is providing more and better data than ever before, and we need an efficient way to disseminate that information. A printed Guide just can’t match the capacity of a digital Guide, and the time is right to make this move. We believe this launch will really demonstrate the power of Glass’s thinking.’

Glass’s digital Guide is available now for cars. Later this year an additional feature of live retail pricing will also be added to the App, giving access to live regional and national pricing information. Additional vehicle data sets will be added in the coming months.
