This would be determined by the terms of the loan agreement and the applicable local laws. Within the loan agreement there should be reference to the action that can be taken to repossess the car should non-payment arise.

Yes, the finance company can repossess the car from the body shop. They would likely wait for the car to be fixed before they repossess the car.
First you will have to pay the tickets and the police will tell you from there.... don't wait to long because storage gets added to the cost.
You can buy as soon as you can afford it. If you expect to get a loan to do so, you may have trouble finding a loan company to do it.
No one can answer this question. It depends on many factors. Here is a thought. Call the lender and ask them.
A company can wait as long as it wants to send a bill in Florida. The money is still due if you owe it, no matter when the bill is sent.

Wait until the vampire misses a payment and then repossess him.
This is highly dependent on where you are at; States, counties and even cities have their own rules on what you can and cannot do to repossess a vehicle, without a court order. Check with your local City or County Sheriff's office. For example: In Corsicana Texas you can repossess a vehicle from any place, so long as you do not cause property damage, but you must FIRST notify the county sheriff's office of your intent to repossess, and show them the papers needed. By the same token, Lake Cities requires that you do NOT contact them about the repossession until the vehicle is at the storage lot, and then you must fax or send them a copy of the paperwork; all other state rules apply. So as a general statement, yes they (you) can wait in the public street, stand on the sidewalk (even) and wait for them to make the vehicle accessible (I have followed them to the store, and ganked it while they went inside; I have taken it from their private work parking, and I have even taken one when they went inside to pay for gas (he was nice enough to leave it running, fill it up, and his date in the passengers seat - I told her to get out, she didn't - no charges filed))
Check your policy it will tell you, states differ, but in my state they have thirty days, and can ask for extensions. They HAVE to wait a certain amount of time minimally (usually ten days or so), to see if the vehicle is recovered.
In the state of SC, most title loan companies will wait for 30 days. After the 30 day mark, your vehicle can be repossessed from your home, job, parking lot or even at a gas station while you are refueling. The repo company they use, will usually be very aggressive and have been known to make threats, which they can follow through with. Calling an officer to assist them, dragging your car away, tearing it up. Unfortunately, it is now legally theirs. They can flip it on it's side and drag it if they want to.
Have the vehicle diagnosed as soon as possible, then you can determine how long you can wait before getting it fixed. Some problems may get more costly if you wait.
