Ok, this is kind of weird, and I feel a little silly for even asking. The fact is that I'm not too sure what year my car is. When I bought it, the guy told me it's an '83 and the pink slip confirmed it. However, the owner's manual is an '82 240 manual. I didn't think much of this discrepency at first until I got insurance for it. The insurance place took down the VIN and said it's an '82. Even some of the repair reciepts stated '82 as the model year. Could it be that my car is an '83 model but built in '82? I still have the original owner's purchase papers and noticed that it was bought in 12/82. Anyhow, this issue came to my attention when I was shopping for some tune-up stuff for my car today. Eighty-two and '83 have some different parts I noticed.

By the way, thanks for all the advice. It's being put to use. While I'm still here, what size spark plug socket do I use. Is it 3/16 (?). And are Fram oil filters good? I remember reading somewhere that it's just as good as the OEM and that a few Volvo places use them. Thanks.
