Hi all, I have a 79 245 and an 84 240GLE. My son will probably 'inherit' the wagon as he likes it , but I am thinking of upgrading to an 850 wagon. I am located in Canberra Australia. Are there any things I need to look out for? And I suppose, what are the major costs involved with these? I am capable of doing a lot of the maintenance but would like a heads up if possible, Thanks all, Paul
