How much does it cost to replace a Suzuki battery?

I’m the proud new owner of a Mitsubishi Outlander, but I have one major issue: I don’t know how to put gas in the tank! Currently, it’s sitting in my driveway until I solve this minor crisis. Where can I find the gas button or lever on an Outlander?

I’m trying to get my car started for my morning commute but my car has trouble starting in freezing temperatures as it’s an older vehicle. Starter fluid usually does the trick, but I’ve run out. I’ve heard that you can use brake cleaner as a starter fluid substitute—is this true?

I'm looking at a car on Craigslist, but the seller claims they do not have the title. This seems like a red flag. I don’t really understand titles though, so maybe it’s not. Can you buy a car without a title?
