Getting a new car with an upside-down loan?

I was writing to possibly get a consult on a dilemma i have. I recently bought a 01 ford f150 from a dealership and seem to be upside down on my loan. I owe $7,000 and is only worth around $4,500. I have found a newer truck that i like that books for $14,000 but is only being sold for $10,000. So instead of waiting to sell my truck out right for the over-bearing price that a dealership asks for, to pay off the lien i have against it, is there a way that i could trade in my current truck for the value to a dealership, and get a loan big enough to pay off the remaining balance of the lien and enough to buy the new truck and put the lien against it? Kind of a complicated question.

Ford f150 truck 2002 keys locked inside?

My mom left the keys inside the truck and the lock is like a push up and push down to open like you have to push it up to open how is that possible to open we're tried a wire hanger to get the keys out of the little thing where you put your keys to turn on the truck. We don't want to call locksmith because my dad said they will charge like 50+ and we don't want to spend that right now it's day time but we need to open it now because if it gets dark someone will see the keys and break our window and steal the car!

I was the victim of a hit and run, is she liable?

I was the victim of a hit and run. It was a head on collision, me driving a ford focus she driving and F-150. I got a good look at her and when she drove past I saw a company logo on the side of the truck, so there's a positive identification on the person who hit me. Is she liable to pay damages if she does not have insurance? Would her company be liable in any way at all?

Illuminated side emblems?

Is it possible to customize a 2006 Ford f150 with illuminated side emblems? I see that they only make them for 2009 -newer but not for 2006. Since a lot of people customize their vehicles with parts that aren't for their models, I wanted to know if it was actually possible?! Has anyone tried doing that?
