previous car was a merc slk 320 and I kept the odd part I noticed was missing on the XF so I didn't have to buy those parts. Every so far has been identical to the merc. From what my mechanic and I can see if its not cosmetic it appears to be straight SLK. You really need to have had an SLK to appreciate just how good the XF is in Coupe form. Much stiffer and far better at cornering, I have just learnt how to scare myself again. Whooooooah
