In the mid '90's air-con gas was switched from the old toxic freon based R12 to a more environmentally friendly R134a formula. For those who switched out their old coolant they got this decal stating 'This car is kind to the Earth / Freon Gas Cleaned', and the month and year of the conversion was written in the 'wheels'. Ideal for those who've ditched air-con altogether or anyone who likes the irony of having this car is kind to the Earth on their high power machine!
