How many amps does a car battery need to start?

I don’t know much about cars, but I’m looking for a used one, and I’ve driven my mom’s Chevy Equinox more than anything else. I figured I’d just get a used Equinox and keep it simple. But which was the best year for a used Chevy Equinox? What year should I try and find?

My son has a used car that he bought himself and drives everywhere. It’s on the older side, and recently, the side panel trim has started to come up. I’d like to fix it myself to save him a trip to the body shop and save some cash. How can I fix the car’s side panel?

Is there a way to reset the oil life in my Honda Civic from 2019? The indicator didn’t reset when I got my oil changed, but I don’t want to take it back to the shop just for that.
