Good Luck SpeedMax. I was planning to get an SRT-6 next, but I am considering the Coupe and your mods. What would it cost to ship to Australia and how long before you have a production version available?
If you are really serious about the XF, then please also consider a wider range of mods (e.g. cold air induction, single turbo, twin turbo) - you will appeal to a wider audience and wallet.
