I take my 5/7/9 year boys in the TTS all the time.

However, the only thing I don't like is that the front sets are rather close to their heads. Once, I had to stop quick and one of my sons sitting in the rear tapped his head on the hard plastic backing of the passenger front seat.

I make it a point now to move both front seats as far up as possible when they're in the back. Of course, I can only take my own seat up an inch or so before it makes it uncomfortable to drive.

I have cabriolet. Is the rear seating more confined compared to the non-cabs? I wonder if this is why their heads seem so close to the front seats.

Thanks.
