Opinion: 20 vs 21" wheels?
I'm getting a new 2009 ML63 next Spring and it has the option of 21" wheels vs the standard 20". I understand that my current 20" snowtires/wheel combo will fit just fine... SO you GL drivers with 21" wheels, I turn to you for advice...go for the 20 or 21? Downsides of the 21"?
Thanks in advance for all your help!
