* Mistral's new, lower annual subscription fee (much lower, the current introductory level Corporate Licence annual fee is £395) is designed to help smaller RAC contracting companies (sole traders, start-ups and educators) enjoy all the same advantages and benefits that all the major firms enjoy.

For just £165 per annum. Probably the lowest price for superior 'Expert System' software in the world! And no! Mistral won't ever hike this fee up. Mistral's annual rates are now, and always have been, guaranteed for life (subject only to inflation of course). Once you become a Mistral Licensee your charges are guaranteed for life ('Fixed in Perpetuity' we say) and you can cancel at any time, no questions asked, simply by no longer remitting your annual licence fee. You won't ever have any account debited automatically. You will receive a single reminder by email to optionally renew, but that is all. Programs also provide 30 days advice of imminent access renewal, automatic Upgrade and automatic Update.
