What’s it with Bollywood and Audi? Shah Rukh Khan bought one for his children and it vroomed in one of the better-looking shots in Baabul. On Wednesday, John Abraham and Karan Johar trooped in to endorse Audi A4 at the Auto Expo on Pragati Maidan. And so did Ravi Shastri, who zoomed away with his teammates in an Audi 100 in 1985 in a splendid tournament Down Under. Strangely, the three didn’t speak much about the lovely machine but kept jibing each other. “If I get the car free for my new film, I’d be happy to take it,” laughed Johar. “And John can act with cars around, and revamp his Dhoom days.”
