You can post your vin# here to have people check. You are getting a hard time because a yellow SRT6 doesn't exist. I would guess that you are probably seeing that the vehicle is a V-6 but it is not an SRT6. Huge difference in horsepower. I drive the exact vehicle you drive and neither one of us has the bigger motor (sadly). This is also a forum of XF fanatics .... the fact that someone doesn't know every nuance of the XF they are selling can be a little mind boggling to us. No one here meant any insult. You have a lovely car in the best color (if I do say so myself). You might want to look at the vehicle value again on KBB if you were pricing an SRT6. The reason it didn't give you an added value for the yellow is of course because an SRT6 wasn't available in that color. I looked up KBB private party good condition (no one's car is really in excellent condition w/ 25k on it) & the value in Winter Park, FL was $14565. Of course your car is actually worth whatever someone is willing to pay for it. Good Luck
