Pros: I did end up with the full-size car that I ordered but not without insisting on what we ordered. The 2016 Impala was very nice and was what I expected.
Cons: we ordered a full-size car and when we arrived to pick it up, they claimed none were available. They offered what was described to be an "upgrade", a Jeep Renegade over a full-size sedan. We needed a full-size car and in my opinion, the small jeep didn't offer the size and comfort we requested and needed. They continued to insist it was an "upgrade" and we should be grateful.
While waiting, I contacted a nearby Enterprise and they had full-size car. Only after insisting on our part, did they agree to have it transported over, which was only about ten minutes. All in all, it was an OK experience but I didn't like having to argue over the size of a car. I even requested a smaller car as a compromise - I just wanted a car - not an SUV.
