Do Illinois toll roads take credit cards?

I was looking to get a used Chrysler 200 and came across a good deal for a 2015 model. Before I make the purchase, what kind of warranty does a pre-owned Chrysler have?

I recently purchased a car, and the dealership told me that I would be paying $658 a month for 85 months and my interest would lower as the loan matures. However, they called me two days later to tell me the bank approved something different, and I would have to sign a new contract where my monthly payments would be higher but I would pay over a shorter time frame. Do I have to sign this contract, or would it be more convenient to stick to what they first told me?

My landscaping company is growing, and I need to add more vehicles to our fleet. However, I’m not sure where to start. How do I register a car under a business name?
