Honda Civic Rental in Portland, OR
This is a basic, very well-maintained Honda Civic sedan. It has great AC, power windows, floor mats, a CD player, and an iPhone 6 charger. It gets great mileage and is very, very reliable.
I have Yakima bike rack that holds 2 bikes, and/or a Rocketbox rooftop carrier available, with a couple days' advance notice, for an extra $20/day.
