I've been told this twice, but I think it's okay if I say it: thanks for taking one for the team
Although if it was this vs. a 2011 Corolla, I would have taken this too. You got really lucky with this since it had such low mileage. Can't believe Hertz would rent a car without a tachometer though. I can't believe how small it is -- look at the single wiper for the front windshield!
You didn't miss anything by skipping the Corolla; I'd go as far as saying this looks nicer. The Corolla engine (although I believe it's a good 30-40 horsepower stronger) is marginally larger, and does worse on gas. The entertainment system looks like junk in your photos but it sounds like it was actually really functional. The climate controls though were taken right out of a Corolla
By the way, was there a clock? If you saw my Corolla report I thought it looked like an aftermarket thing. I don't see a clock at all in your Yaris
Overall I really enjoyed reading your report. I think this is the smallest car that's been written up (other than a Fiat 500); it's great to know what you could end up with on a cheap reservation. I'm glad you have fun writing them like I do too

I'm contemplating adding some comments to your Camry report or writing a full-fledged one myself -- I got one on an A reservation (!), and I have quite a bit to say about it
