Bought my XF in April of 2008 with 595 miles on the clock. Love the car, have done a few mods mechanical and appearance. Just got back from getting new tires a few minutes ago. Bought the new General G-MAX A3-03. Decided to keep stock sizes. took it out and ran it up to 100mph, smooth as silk. Kept my two front Cont as spares as they weren't worn much. Brought it back home washed and cleaned everything, gave it a little polish while I was at it.
