All the Camira variants from Holden have air con so I will be doing a conversion at some stage and do a write up... the misus demands it if it is my daily driver. Yeah the parts people are selling are from the Camira variant, which is plentiful here. You would think a Cabriolet would be the go and for sure at morning and evenings but I live in Brisbane QLD and it's hot here in summer during the day and you often see people with the roof down but wearing a hat lol. I have seen some surface rust middle rear hatch below the glass and above the spoiler, passenger arch and on the bonnet but this is just surface rust from lack of paint. The paint is crazed and cracking all over the roof. There is some rust next to the rear hatch top hinge and so far that's all I know about. Antony
