How much should I be paying for GT4 PPF installation?!

[GT4-BaV]

Hi Guys,

I'm a long time lurker on the forums and have recently had my GT4 order lock in for a March delivery. Colour I've gone for is Sapphire Blue Metalic.

I've seen lots of talk of full correction details and PPF install pre collection so would like to hear from you guys that have had it done or at least looked into it.

If anyone with experience can let me know what they had done with a rough price that would be great.

Thanks in advance!

Richard
