I want to buy a jeep Wrangler and...?

...I wanted to know some things.Which type of Wrangler is best.Also,I want a Hard-Top,but I was wondering if you can get second row seating if you have a hard top.Basically,I want to be able to drive friends,but if there's no backseat,I'll have to rethink it.And no,I don't want to settle for a new one with four doors.They're ok,but expensive and not really my style.Finally,which Wrangler gets the best gas milage(if it were mostly stock).
