Ill agree with most of the others here...wow... thats a lot of rust, and being from the rust belt, Ive seen plenty.

Its been my experience and many others will attest, that its always easier to start with a solid rust free, or fairly rust free uni body, frame rails, floor, trunk, etc...and then go from there.

One of my prior birds wasnt as bad as that one you have, and I passed on it knowing how much time, effort and money would be spent on just the structural integrity for safety reasons. Then to add in the other interior, electrical, brakes, fuel, lines, drivetrain, and never ending body work...wow.. you really have your hands full there.

But hey, if you're up for the challenge, then go for it! All the parts are obtainable if you have the funds, and judging by the looks of things, you'll need deep pockets. But you'll learn a lot in the process. And even if you decide not to venture on this one, you might have a decent donor car on your hands or a frame/goodmark candidate as mentioned.

Since you're already asking about the routine maintenace stuff, Id suggest you order the pontiac service manual for your year as it will come in very handy...

Good luck!...and have fun...thats the whole reason we work on cars...right?
