Just some notes on my
Alamo rental experience, from about 11am on 8/3 to yesterday, 8/12 at about 5pm:
I booked a Standard with the Insider's discount and the Visa $30 code (AD2338FDF). I checked in online so I did not stop at the counter or a kiosk.
In the full size row, there were several Impalas, a couple of (dark colored) Altimas, and to my (almost) delight, a white Passat. But I opened the door of the Passat to a breath-taking smell of car deodorizer that would surely give me a headache. And I *didn't* know what the car would smell like if and when the deodorizer smell faded.
I went down the row looking for a lower mileage Impala. Most were in the high teens and dark colored. I found one that was around 10k but it made a funny noise when I started it. I went to the booth and asked if I had any other options and the nice manager took me to the National Executive Selection aisle where I opted for a 2014 Silver (2?)LT Impala with about 5500 miles on it. I was pretty happy with that!
At the gate, my $30 Visa code had mysteriously changed to a free day so I'm glad I looked at the paperwork and saw the total didn't match my printed confirmation. Without the code, the agent could do much (quickly) but luckily I was able to find it on my phone. She keyed it in and, voila!, the new total matched my expected number. (So write down that code just to be safe!)
Overall, it was a nice car. BUT the rear passenger window did not work (at least it was stuck closed!) and there were electrical clicking sounds coming from that door every so often. And a little past half way into our trip, the check engine light came on. And the remote start stopped working. (I assume related to the CE light.) Not cool when you're coming back to the car in those hot, hot theme park parking lots! It's nice to start it up when you get off the tram just to take the edge off the built-up heat. (I reseated the gas cap but the CE light was still lit when I returned the car after several starts and 70 or so more miles.) I told the agent about the issues when I returned the car. No extra discount was offered, but at $179.xx for a 10 day rental, I have no complaints.
As for the 2014 Impala, my experience is only one data point but I'd pay attention to reliability ratings before buying one - or wait for the 2015s. (But I'm still happier with my 2012 Hyundai Genesis - which didn't cost any more than a loaded V6 Impala - except for the remote start and the longer driver's seat bottom. The Impala won on those two points.)
