I bought an 04 with gray interior.
The next day my friend bought the same car with the ivory interior.
Today mine look like new, her's looks like crap.

Look at any old car with wear and tear and stains.
The wear and tear itself looks more gray than ivory.

If your concern is interior appearance over time get the gray.

(Just one opinion, you guys with ivory interior don't shoot me.)

Need fewer troops to support.
Drive a hybrid.
Best tank 71.65 MPG.

Before this car I spent two years learning hypermiling on my 2004 HCH1.
