2011 Dodge Caliber

I have a 2011 Dodge caliber I bought a few months back with a 170000 miles . Will need battery it will start right up , all lights work. Heat and air conditioning works. Everything that is power works. I did install an aftermarket TV screen and backup camera. It does have an exhaust leak which causes the car to be loud not super loud but loud enough to tell there’s a leak The check engine light does come on , not sure why it hasn’t really affected the way the car runs and drives, probably could use a tune up .Small rust spot under driver side door. Rear struts could possibly need done, I only say that because there is a slight knock when you hit a bump other than that the car runs and drives pretty well. Understand I would keep this car but I have to big of a family I need something bigger looking for third row seating. Daily driver so miles will go up
