Jag had good reason to celebrate the past, as this year marks the 75th anniversary of the Jaguar name. Of the 16 XKSS models -- arguably the most beautiful and iconic Jag ever made -- the British company, now owned by India's Tata motors, managed to bring 12 of them to the party. At the kickoff, corresponding to a "Gentlemen, start your engines!" announcement, each owner started up his car and saluted the attendees with some throaty exhaust notes.
