I'm starting to see some rust on my 1982 245 rear hatch. I've seen some in the boneyard from later models, and have been wondering several things: 1) What later years might fit my older car? 2) Are the newer hatches made of different material to resist rust better? 3) Are the internal mechanisms compatible?

On another matter: I've had power windows in other non-Volvos I've owned and hated them as I found them unreliable and thought them unnecessarily complicated. I've noticed that many later Volvo 240s in the boneyard have power windows. Whenever I start looking for another 240, I'd like to be able to avoid power windows if I can. Did power windows become standard in later models?

Thanks in advance for your help!
