bro...platinum look (or makintab) was great during the 1990's

..keep your car simple and classic looking...stay with a standard shade or tint - gray or black. good for when you re-sell later as well.
* further note - count how many standard looking tint you see and compare it with na lang with cars with makintab/platinum shaded tints...not many with the makintab look right?

.
and WTF in regards you having to fork out more money for your tint? Take your money back and tell them you just want the normal free tint usually available. If you want to upgrade later, do so and use your 3k towards this.
end of the day tho, your car, so you have to be happy with your end choice.
