Britain's May Day bank holiday is derived from an ancient Roman festival marking the first day of summer. For 2020, the May Day bank holiday has been moved to May 8th to coincide with VE Day, which this year commemorates the 75th anniversary of the end of WW2 in Europe. On top of that, Classic Retrofit celebrates its fifth year in business this month!

We’re celebrating the arrival of summer and these special anniversaries with a cool little discount for all would-be customers of our cutting-edge air conditioning kits, as used in the legendary Singer and Ruf 911 creations. Add one of our upgraded six-phase Porsche 911 alternators to any order for one of our electric air conditioning systems - either a full kit for all air-cooled 911s or a half kit for later air-cooled cars - and get a 15% discount on the price of the alternator: a potential saving of over £130!

The discount is available while stocks last. Simply add your choice of electric air-conditioning system and the appropriate alternator for your car to your shopping basket, enter the discount code MAYDAY at checkout and the system will do the rest.

We are shipping worldwide daily throughout the pandemic and have all systems in stock ready for immediate despatch. Contact us with any questions!
