The 20 minutes you saved by going to Enterprise, was ate right back up by the time it took to stand on the line, get processed, do a walk-around and still have to go back inside to the counter. I would have just went to the National location. Last time I called in for a mechanical swap, the location was notified by National and had my contract & new vehicle waiting for me; same model. I was back out the door in 30 seconds.
