Just did my first UC rental, out of SEA. SEA were never a great station for Gold Choice but Ultimate Choice seemed alien to them on the evidence of today.

Gold, midsize, fullsize and 5* were basically interchangeable - any flavor or make of Altima you like (Nissan, Kia, Toyota, Chevy, Hyundai...) with the occasional actual midsize car and one 2016 Impala Limited holding on. (I was tempted to take it as a flashback to my first US rental nine years ago, but passed).

In PC it was 80% the same as the other areas. I don't think I saw a single SUV, minivan or coupe/convertible. Happily they did have a couple of Q50s, two Chrysler 300s and a Maxima SL, which I have. They had some seriously nice cars in the $25/day upgrade line - only to be told that, despite the signs "We don't do that any more - we do have the Gold Choice area but they're over $100 a day.") So a definite case of the station not getting the concept whatsoever.

Should stress that the guy at check-out was excellent though - polite, friendly, helpful and competent.
