Hello guys I've been a member on here for a few years but haven't really been on..( more to do with the fact no one would insure me on a 260)

But it seems now I can be get insureance for a 260, I've been in the mg family for a while, currently own a 75 contemp se cdti, a mg zr t16 and a mg zs td( that belong to the late father and ongoing resto)

i am am just wondering guys what are the main faults with the 260 and which parts are no longer available...?
What about those rear arms .?
