Tallen234,

I too am in AZ and am planning on tinting my black saphire x5 once it is delivered. Where are you looking to get yours done? The only recommended place I've found so far is Danny's in N. Scottsdale and they only sell HuperOptik. I am currently set on getting the HO Stark 30 (ceramic) on all windows. I find that it's best to get the same shade from front to back so that it looks like a more professional finish. What color is you X5? If I were going with a lighter X5, I might get the Stark 20.
