I swear that some folks are talking about a different dealership. My wife and I have been customers of Piehler Jaguar for 20 years. We'll soon be picking up our 5th Jaguar, all of them purchased at Piehler's. I find the sales department, especially John Morris, to be friendly, courteous, and knowledgeable of the cars that he's selling.
I also found the service department, the few times our cars have needed service, to be very competent and accommodating. And when doing some "home maintenance", on an older Jaguar, the parts department has always gotten me the parts I've needed, in very short order.
