What are typical Alfa Romeo maintenance costs?

Yesterday on my way home from work I noticed my brakes were acting weird. It sort of feels like they’re “skipping”, almost, like my foot is held down with steady pressure, and the brakes get loose and then get firm again. I’m not driving the car until I get to a mechanic, but what can make brakes feel like they are skipping?

I tried to do a minor paint touch up for the first time. After I thought I had finished and had already added a layer of clear coat, I noticed that I didn’t use enough paint to cover the scratch. Is it ok to paint over a clear coat?

Is there an easy way to check if my car has a kill switch? I know they can help prevent theft, but I’ve also heard they can be dangerous.
