2004 starting to show its age.
Here is a picture of my 2004's armrest. The car has 56,000 miles, and I have a 13 year old and a 3 year old that do their best to destroy the car. It probably hasn't been vacuumed in six months, hasn't been shampooed in a year. The only major problem is the front of the fabric keeps coming out from its 'wrap around', so I have to keep pushing it back in. This started at about the 40,000 mile mark.
Owner of 'Eeyore', a 2004 Prius. Only took 2 days from start of search to delivery.
8 years of ownership, 115,000 miles, about 40 MPG average at present.
