£170!!!! Ya joking mate i had one fitted by autoglass about a month ago and it cost me £350 fitted
It was a complete nightmate too they messed me around so much getting the wrong screen and wrong tint at the top, i ended up with an s13 screen which is just the same accept it has a small black square where the boss of the rear view mirror sits but you cant see it behind the normal s12 mirror so its all good.
Good luck in getting one and i hope you dont have the greif i had
