Just bought my white deluxe last February. I searched all over for a matte silver deluxe but nothing was available within 200 miles of me so I decided to check out the white deluxe since it was local. Just my two cents but I was not disappointed for one second with the white. Looks great out in the sun and I get compliments all the time when I take it out.
I would vote for the white deluxe with warranty between those two choices, just in case you give a chit. :-)
Good luck with which ever you choose.
Peace
