This van is back with a picture of the rusty underneath... Is that bad rust or not so bad rust???
Is there any such thing as good rust?
Seriously, what I could see didn't look bad at all. In fact, that looks about like the normal underside of most cars out there.
Go take it for a test drive, see how it steers and handles. Drive it over a bumpy road while listening for anything that sounds loose or not normal. Drive it on the freeway to see how it handles at speed. Don't be afraid of giving it some gas. Drive it long enough to get good and hot, and see how it reacts to that.
Funny story here. I kept going to a certain used car lot because they had a car I was interested in. They kept putting me off saying the car wasn't legal to drive yet. Finally one day they said OK, but the salesman had to go with me, I drove the car around the neighborhood a bit, then told the salesman I was going to take it on the freeway to see how well it handled highway speeds. It went well, so I drove back to the car lot while telling the salesman I really liked it. When I parked it in front of the office with intentions of buying it, all of a sudden smoke started boiling out from under the hood. After opening the hood to see what it was, it just appeared to be la serious case of blow by.
I got out, handed him the keys while stating I don't think I'll be buying this one today. The salesman didn't argue, but just took the key, and I left.
Now I understood why they kept delaying. They had apparently filled the engine with motor honey with the hopes of suppressing the smoke from the bad rings.
This is also why I took it for a good long ride, including freeway speeds, and stepping on the accelerator briskly at times. This will loosen up the motor honey, and if it's going to leak, this will eventually make it do so. This also saved me looking at the oil to see if they had done this. At this point I was done with them, never to return. They got to watch me with money still in pocket walk away.
Remember, if they are afraid to let you drive it like you stole it, they are probably trying to hide something.
OTOH, just about every time somebody just handed me the keys and said have fun, I bought their car.
PS, I ended up buying the same model car from a private party much later and it's been a real gem.
