Very nice lookin' rig. As far as mods go, I'd wait until the warranty runs out too. I know I'll be modding mine when the engine hits 100k miles (bought mine in the US). I had an oil leak at the bed pan and a couple of other little issues and Ford covered it under warranty...Their bill $4900. When I saw that, I was glad I kept it stock!
You could start doing outside mods...I've got a gooseneck hitch, put in a roll up aluminum bed cover. added window vents, stainless running boards are next. Then comes the exhaust, intake, ahem delete kit, and all the other goodies.
