Yes, but he/she should not drive the car until after his/her name has been added in the event your insurer requires it.
If he lives with you and your insurance company requires you to list all household drivers, the 19 yr old should already be on your policy. Even though he/she has not previously had a car purchased for them, they have access to your keys and your cars in the event of an emergency insofar as the insurance industry sees it.
Certainly. You can insure any licensed driver you want as an operator of your vehicles.
Around $12,000 per year
Yes, you can. List him as a driver.
Most of the major insurance companies will insure a previously uninsured driver. Your premiums will probably be higher though at least for the first year until you get some insurance history under your belt.
Usually you have to insure your bike for a full year, but then they may have a diffrent shceme for it.
Yes if you can find an insurance company that will insure you. You're looking at the neighborhood of around $15,000 per year just for insurance. http://au.answers.yahoo.com/question/index?qid=20080206172626AAIYZE4
More than payments on the vehicle if you can find a company to insure it. No one will insure it in the name of a 16 year old insured. It must be insured in the name of the owner and the driver (16 year old) must be listed on the policy as principle driver.
£270 a year
Yes.
Yes, IF they have a driver's license and not just a permit.
No major car renter offers rentals for 19 year olds as the primary driver. You can circumvent this if your parent is willing to rent the car and insure you on it. E-Z car rental will rent to a 19 year old, but at a higher rate
No.
