Hey! My car is a 2012 Toyota Yaris 4-door liftback. Its a simple and dependable machine. It looks tiny on the outside, which is good for parking in and around Seattle, but feels like a normal car on the inside, nice and roomy. It also gets absurd gas mileage. This car would be good for an IKEA run as long as you aren't getting a whole living room set. The back seat folds all the way down and it becomes surprisingly roomy back there.
Its typically available on weekdays and on some weekends. I work full time so key exchange can only really take place fairly early in the morning (between 730 and 830) or in the evening (6pm and on), but let me know and we can make alternate arrangements if none of those times work for you.
