How much does it cost to fix a misfire?

I recently totaled my car and after the fact, I also realized that the title has been misplaced. Since I was planning on junking the car anyway, am I able to legally junk it in Illinois even if I don’t have the title?

I had a friend help touch up my car’s clear coat, but he went a little too heavy with the spray paint and now I have a couple of runs that stick out like a sore thumb. I just hope this is easy to fix. How do you fix clear coat runs on a car?

I moved a little less than a year ago, and it never occurred to me that I needed to change the address on my license. Nothing has happened so far, and it doesn’t expire for three more years. Can I just leave it as is? What is the penalty for not changing the address on my driving license?
