Similar experience with VW Palacecross. I've spent close to 3 weeks after having booked that POLO Highline MY2013 .
They have no idea when the car will be delivered and have confirmed to me that whatever Diwali scheme's that i have opted for will be null and void when they deliver the car. They want more money now to sell me another variant.
I have just cancelled the booking and awaiting my refund for the advance amount !!
Please do not deal with VW palacecross . You'll be very disappointed with your desire to own a new car !!
