My Porsche Cayenne battery died while I was in Europe for a few months ... I needed it replaced urgently before I left San Diego for a trip to Asia. Ordering through the website was fairly easy and I received a prompt confirmation. I had a bad experience (with another company) with a service in Hawaii for my wife's Mustang when the technician they sent did not have the correct connectors for the car (I had to order and replace them later). The pre-service communication was OK but not great which caused me some concern as the battery replacement for a Cayenne is fairly complex. When the tech showed up (on time), I asked if he had done a Cayenne replacement before and he said 'yes' ... sure enough, he knew what he was doing and did the replacement in less than 30 minutes. I am very pleased and the only reason I didn't rate you at 5 stars is the weak communications on the day of the appointment. You will be my 'go to' company for battery replacements going forward.
