Since 1933, the company has been bringing invaluable insight and intelligence to dealers around the country, helping them to run more efficient and profitable businesses.

Managing Director Ian Tilbrook said: ‘We’ve been the industry bible for more than eight decades, and we are really proud of our history and heritage. We are as committed to customers today as William Glass was back in the 1930’s, and we are delighted to still be providing them with a Guide all these years later.’

As part of the festivities, Glass’s has produced a nostalgic cover to this month’s Guide, and is taking a trip down memory lane through a twitter campaign, which takes a look back at old automotive adverts, iconic vehicles and values of days gone by. There’s also a chance to win £25 for and £25 for charity throughout July in Glass’s Friday Bingo giveaways.

Tilbrook continued: ‘We really do have something to celebrate, and what makes this anniversary so special is that it coincides with the launch of our new Digital Guide – we’re moving to the next chapter in Glass’s history, and we look forward to another eight decades supporting the industry.’
