You're on a 7 series forum... let me break it to you now, the results are going to favor the 7.

Honestly in this scenario, it comes down to looks. Does he like the look of the 7 more? Or the S? Both have extensive navigation systems, excellent comfort... the 7 will drive better, but the S looks more upscale.

Both are excellent cars, he can't go wrong.
