I have 14,000 miles on my XKR now. I have to say that I do like the car. Although, at 8,000 miles the motor developed a ticking sound. I brought the car into service, they discribed the sound as a knocking sound coming from the lower part of the motor. Well, needless to say, they replaced the motor. I still wonder if the new motor will develop the same knock..so far no. Anyway, I was wondering if any of you purchased a rear wind deflector. I am considering one and looking for vendors. Any help would be appreciated.
