My older XJS had issues that this dealer made worse and very expensive by not telling me that the service staff had insufficient knowledge of how to understand and diagnose the problems of an older jaguar. On numerous occasions I would be told that the car was ready, then find the same or another engine related problem when I started to drive home. Whatever they did made things worse. This included, but was not limited to, severe and dangerous engine racing which required me to apply mighty pressure to stop the car, and severe and dangerous (dead spot) hesitation/stalling when accelerating from a stop. Over more than a month I was started on a trend of "let's try one more thing" that amounted to $4,500! Eventually one of the advisory staff told me..."look, these guys know how to read the electronics of newer cars on their diagnostic machines, but are clueless with "real" engine mechanics." In frustration I finally took the car to a foreign car repair shop in Alexandria, and they read the older electronics via bridle hook up to the engine and fixed the racing and hesitation/stall problems in one day for $150.00!! After so much frustration I was thrilled. If I had only gone there when the Rosenthal dealership issues had started to surface! BIG mistake of not correctly reading the situation on my part. Also, rental is only covered for 2 days if the car wasn't purchased from them...so add that inconvenience to my horror story. NEVER EVER take any car resembling vintage to this dealer.
