welcome to the nova site. there's lots of nova out there for sale from a few 1000 dollars to the sky is the limit. some will need a small miracle to drive again an others are ready for a cross country road trip. also the body is the hardest to fix an takes the longest time to repair.
There's a for sale section here. I haven't checked it out, so I'm not sure how active it is. I scoured Craigslist (like the whole west coast Seattle to LA and across the south west to Texas) for about 3-4 moths before I found one I liked. Welcome and good luck.
