Great link, Rob!
The stats are interesting. I'm surprised to see that my option choices are most all in the low percentages--maybe my car is one of a kind--though I don't think that makes it any more valuable.
I didn't know there were choices for rear axles!!! My salesman never mentioned it, but if I could choose now I would go with the higher ratio (lower gearing) 3.63:1 axle... I wonder what it would cost to change it out?
