We're still looking!

We discovered a MB MY13 GL350 is a very tight squeeze, almost impossibly tight, to get into our garage. At least it was fitted with the camera pack.

The D4 HSE I test drove last week didn't have the front cameras so it was even harder.

The D4 is a fair sight cheaper ($40k!) but one of the things I did like about the MB were the blind spot warnings (visible and audible) as well as the lane departure warnings. Is anything like that available for the D4 or slated to be an option in the near future?
