Side Mirror Glass Repair?

I hit my 2008 Honda CR-V today. One part of the damage is that the driver side mirror lost some glass. The glass will need to be replaced. How much does it usually cost to replace the just the glass?

I have a 1997 Honda CRV all wheel drive. And it keeps overheating?

I have checked all of the fluids and they are full. There are no leaks from the radiator or hoses, the antifreeze is full and the car keeps overheating. I haven't replaced the thermostat yet but is there something else that I'm NOT checking that could cause it?

My car battery died for leaving headlights on for about 50-60 minutes?

So I took my brother to practice and I left the headlights on for about an hour, when I got to my car I then realized the car wouldn't start, so my brothers coach comes and jump starts my car, so after that it took me about 20 minutes to get home, when I got home I turned the car off the car and after I turned it off I turned it on and it worked still so my question is will it work by tomorrow morning? I don't have any info on how old the battery is I just got the car this week but will it work by tomorrow?

Added (1). O and it is a used 2002 Honda CR-V

Is the new Jeep Cherokee good off road?

Specifically the base Sport model with FWD. I know it's not gonna be rock crawling or mud bogging, but with a good set of all terrains, could it handle occasional dirt roads/trails/wet grass?

Do the base models have under body protection? I mean I could just buy a Honda CR-V or Toyota Rav4 if it's at the same level.
