I stopped back by this location this evening as the car I am in has a buzzing in the front passenger speaker.
They were unable to swap my car out as they were holding the other Altima back in case they had a walk-in

.
I noticed something interesting in the meantime. It appears that my car having 43,000 miles AND temporary plates is not a fluke. On the website, it lists the Ford Fusion as the example SCAR. Finding the "new" Fusion to be a better rental than the Altima, and surprised at the SCAR classification when most companies are now listing it as FCAR, I was hoping there would be one on the lot for me to be able to swap into. Indeed when I pulled up there was a Ford Fusion with a temporary tag pulled up at the front of the office, but it was, wait for it, a 2012 or older model!!! Yes, it was a previous generation Fusion. It seems that this location buys used cars to rent out in their fleet!!! I have seen this before amongst franchised locations in Europe, but have never seen this in the US amongst the major car rental companies.
I know that operations such as Rent-A-Wreck and local car rental companies do this often, but I would have expected much better from Sixt, particularly in the US where they are trying to rapidly expand their market share

Also, almost all of their cars have noticeable to significant damage including deep keyed marks covering the rear passenger quarterpanel of my vehicle (which I did not notice upon checkout as it was dark, but they admitted was preexisting before my pickup).
