I rescued a 2wd saph that had been stood for abt the same sort of time. Thought it would be all hunky dory (my first cossie actually) but oh no......rings gone, overheating, calipers seized, floorpan gone in 4 places and so on. But it was so worth it; the satisfaction you get when shes all up and running!! Plus you learn so much by doing so! To me, that's all part of the fun being a cossie owner! Hope you don't lose heart to quick mate.
Cheers, Chris
