Why waste your time and theirs? So you can get a thrill while using and abusing someones elses things?

Why not go and rent a luxury car to see what it feels like?

Should I charge gas money? If so, how much and when?

I just got my car. It's a big black 1999 Ford Explorer. It gets 13 mpg in the city. When I first got my car, one of my friends stopped picking up one of my other friends (Sommer) because she felt like Sommer was asking Lily to take her too many places. So I told Sommer I would pick her up for school AND take her home. Well, she asks me to drive her all theses places and promises me that she'll pay me back. She did, but it was only ten dollars. If you have an SUV, you'd understand that ten dollars is like a drop of water in an ocean.

nothing will happen to it BUT most will recommend that after changing jobs you roll over the 401K into another account that you have easy access to. People change jobs and addresses and forget where their money is.

I recommend opening an account at an investment firm like Fidelity or Vanguard and rolling his account directly into it. If he changes jobs again you can do the same and keep the money in one place. An account Rep at either place will help you with the rollover to ensure it is done correctly and avoid tax penalties if you just take the money out yourself. Once the money is in the account you can invest it properly for retirement.

Can't speak to your anti-theft system but on many car radios if they loose power for too long you have to put a code into it to re-activate the radio. They do this so no one will steal the radio as it will be useless without the code. The code is usually in your owners manual or on a small card that comes in the packet of information you get when you buy the car. If this is not the problem you may check the fuse for the radio, perhaps it was blown when you changed the battery. I would guess the security system has to be reset, check the owners manual or call a dealer.

Even if you fail the test, it' not like it matters much, you can try as many times as you need until you get it.

Once you've got a license, you'll wonder how you ever lived without one.
