Thinking about getting my windows re tinted as the old purple tint looks ghey.
Was just wondering how much it usually costs and how dark can I go?

Best bet to go to a car tinting place for a quote.

But a good idea is to remove the old tint yourself if you can as they WILL charge too much (in my opinion) to remove it for you. I found the best way is to use on of those plug in steamer things you can buy for cleaning BBQ's, showers etc. Just let the steam and heat get under the old tint and it peels away no prob.

i got a quote yesterday from solartint in sydney!
they want $395 to tint the whole car in there top of the range black pearl! (35% )wich is the darkest
legal tint available.
and they wanted $100 bucks to remove the old tint from the windows.
but if i reply to there emailed quote i will save $110 dollars overall!

Just had my chrome/black fader redone on the door windows of the ute for $160.
They had to go darker than before which I dont mind, it;s illegal anyway =D
