Diesel fuel in my car?

I accidentally put some diesel fuel in my car. It's a 2012 Honda Accord sedan with a 4-cylinder engine.

I had pumped about two gallons of diesel fuel into my car's gas tank when I realized what I was doing and stopped. I then filled the rest of the tank with nine gallons of regular unleaded gas.

To be on the safe side, I had my car towed to a garage where the mechanic was able to drain the diesel fuel and clean out the engine, gas tank and gas lines, and the fuel pump. He said that diesel fuel is one of the worst things you can put in your car. Will my car be permanently damaged and if so, how? Or did I overreact?

No money to pay for an at fault fender bender?

I'm a broke 17-year-old high school student. I recently was involved in a fender bender where I was at fault. The guy I hit was driving a brand new 2017 Honda Accord. I hit his bumper, leaving small dents but disordered the position of his bumper As well. He's in process of getting an estimate from a body shop I directed to. The car I was driving in, under my dads name was uninsured but we live in NH where it's not illegal to have an uninsured vehicle. I'm currently unemployed but plan on getting a job and have about $200 in my savings. I don't want my dad to worry about paying for me so I will work to pay off. Without having enough money to pay out of pocket up from, what should I do about payments? Is it possible to ask and pay monthly? Suggestions?
