Did ford dealership rip me off?

So my car completely died back In November so I had it towed to Ford because I needed my car the next day for holiday travel. They replaced the battery and everything was good. Well I just got my oil change at valvoline today and they said my air filter tube was disconnected. So they connected it back. Do you think Ford disconnected it and forgot to connect it back? Or was it just to cause more issues with my car? I normally don't go to Ford for servicing or for anything really unless I think something may be covered under warranty… Which nothing is ever covered. Learned that the hard way. I did notice tho that when I got my car back, it did seem a bit off but ever since they connected that tube back I haven't heard anything.

3 prongs for sealed beam lamps not fitting in connector?

I just replaced the lamp assembly (H6054) on a 98 ford e350 and only managed to get the prongs half way in, though they still work. Since i didn't bother to examine the way it looked like before, i don't remember what orientation the connector was in. Is this normal or do i have to fix it?

Why is my car leaks oil and coolant?

I own a 2002 Ford Windstar. White thin smoke comes out of the engine, it leaks a lot of oil when I drive it. The let's out a sweet odor while I drive it which is unusual. Someone started my engine and said the what pump leaks and noticed the car needs water. They say it's leaking coolant from under the car but to me it looks like oil. Can you tell me what is wrong with my car and how much it will cost to repair it.

Added (1). They said the water pump leaks coolant. The inside of my car smells sweet when I drive.

How much money should I expect to get from selling my 2005 Ford Fivehundred without a transmission?

I've been trying to sell my car for a while, and I had a guy offer $350 for it as his final offer. That's a lot less than I was hoping to get out of it, but I also haven't received many offers. On the other hand, I could sell it to a junk yard/ junk car company, and possibly get more money out of it. Half of me is wanting to be nice and sell it to the guy because he really wants it, but the other half is telling me to try junk yards for more money. What should I do
