Using money that was given to one to keep as an amaanat (trust)

Q: I would like to find out about some money someone gave me to look after.

Now I have used some of it for myself and haven’t told them. But in my mind I know that I have it and will return it when they ask for it. Is this ok, or should I have asked their permission before using it?

Also, I have put some of the money in an Islamic bank which gives some profit. My question is do I have to give them the profit as well as the money they lent me or just what they originally gave? 

Buying a car that was named after a zodiac sign

Q: Is it permissible to buy cars made by Ford as they have a car named “Taurus” which is the name of a zodiac sign. The company probably kept the name on the constellation of stars or name of zodiac sign. I don't know if people associate it with the zodiac signs or not.

Would it be permissible to buy this car (Taurus) from this company or any other car from this company (Ford) ?
