I booked a 2-door Wrangler, but the staff strongly recommended upgrading to a 4-door Wrangler for an extra $35 per day. I refused. When I went to pick up the car, they didn't have the 2-door Wrangler and gave me a free upgrade to the 4-door Wrangler. It's not sincere to push for a paid upgrade when the original car isn't available; a free upgrade would have left a much better impression. Other aspects were fine, the car's condition was acceptable, and the return process was quick with a final receipt provided.
