This is brand new Prius! I just bought it and it's a 2014 model, with level four trim. This just means that it is an amazing car. The trim includes navigation, satellite radio, bluetooth, heated seats, a fancy sound system, and a bunch of other luxuries you probably wouldn't splurge on in real life:) So just take advantage of these now while you're renting! You'll also fit in exceptionally well; driving a Prius in Portland is almost as popular as having a beard.
This car is perfect for city driving: it's small enough to fit into many parking spaces (especially with the new built-in back-up camera), but large enough for trips to Ikea. It's also great for day trips to the Columbia Gorge or the Oregon Coast, since the mileage is outstanding. I average 45-50mpg in this car and there are different displays that allow you to track your gas use/cost. It is all around a great car, for whatever you need to do!
