Well another update, my air conditioner system failed on the hottest day recorded yes the 45 degree one about a month or two ago...

Got quoted 1500 which I believe is reasonable, but my mate reckons just get rid of the car and get a new one as you never know what will happen next with 200k+ cars in general.

I want to fix the system myself, any ideas where to get parts or a guide on how to do it?

I also had the actuators fail a week after the air con, which I have got a mate to fix this weekend. We also noticed this weekend that the car sometimes doesn't start when i turn the key (weak batter or starter motor?)

Engine is great, ride is great, everything is great...apart from the above.
