My 1968 '07 had power steering. Earlier this year, I purchased a 2006 Pontiac Torrent SUV and I can tell you, my 07 was easier to drive that this piece of c.....but I digress...
Why not fix what needs to be fixed and sell it. You have to weigh the cost of such.
If it costs $5000 to fix it, and its only worth 3k, then you know you can't break even. But, if you happen to have a spare 8V71 laying around and you're pretty handy mechanically, then why not try to fix it yourself. I agree with previous posts. It ain't worth much as is.
Getting back to that Pontiac Torrent...(I just can't let it go). When we looked at it, we loved it. It is a sharp looking ride. Then we test drive it, and my wife just has to have it. I cannot believe I traded a 2005 Honda CRV for this thing. It drives like a tank, has no leg room for the driver (passenger has plenty) and my knee gets sore from rubbing against the drivers door. I never knew when my Honda was cranked because I couldn't even hear it running. This thing sounds like a freakin deuce and a half. And, what the heck is wrong with GM that they put the cottonpickin gas tank on the passenger side. I'm forever getting blowed at by other drivers who think I'm pulling in the wrong way to the pump. The back seat sits like a dang milk crate. Man, I can't believe I traded my CRV for this thing

...but at least I'm supporting America, even though most of it was probably made in Mexico.
Sorry for this rant, I don't know where it came from...

But good luck with your thing bigred.
