I want to buy a used Nissan Leaf but....

I want to buy a used Nissan Leaf because I need a grocery getter to take my dog to the park but...I don't know anything about them.

1. I live in a very large metro area. They are not popular here because of their more limited range. Because I will have more than one vehicle, range is less of a concern...but what will it be for one with 30k miles, 85k, 125k miles?

2. Can this be plugged into my dryer outlet in the garage? I don't want to add an outlet. Can it be charged at a Tesla station? How long does it take? How much does it cost? What about taking it on the road?

3. Tell everything about the batteries.

4. Does this have the same transmission as a Versa? Is that a problem?

5. Common problemss?

6. How do I make sure that I am not being taken on the purchase?

Thanks in advance..
