We are 3 adults planning a week long car trip in an open car. The rental agencies are offering a choice of either the A4 or the CLK. Which of these two offer the most space for the guy in the back? We're all ~190cm tall, so this is important.
Also, how much luggage space do they have with the top down? I've found a figure of 390l for the CLK, but surely that's with the top up.
