[DL335D]

I was in the exact same situation. I went with the grand coupe. It has a huge trunk/hatch and it looks so much better. I actually prefer it's looks over my F80. I feel that it will age more gracefully too.

The 340 definitely felt quicker and sounded slightly better, but for a few tenths to 60. It wasn't worth it to me. 5 seconds to 60 is plenty fast enough.

It I had to do it over again I would have went with a 2015 640. Even better looking, way better interior and much quieter cabin.

Here is some eye candy for you...
