Hello, I am currently repairing a 1980 Mondial 8 in green. It has been stood indoors for 25 years! It is rock solid with no rot. It is the only green one ihave ever seen. Could it be a one off? Is ther a way I can find out? Will it be ok to run on unleaded? Is there a modern replacement available for the aircon pump? I think the original has bit the dust..... Any help appreciated!
