Thats awesome, I wasn't expecting that, but how much space does the driver have with the front seats pushed all the way back? Did you also sit in the front seats and adjusted them?
I hope there's sufficient space for the driver and front seated passenger.
I sat in the front and messed around with the seat within reason. When I first got in I couldn't reach the pedals, slid it up quite a bit from what I assume was all the way back for a comfortable driving position.
My main concern was w/ driver seat adjusted for me and passenger in a comfortable position, no knees in chest, could you fit 2 reasonably sized people in the back. The answer for that is definitely yes, and with a 6'+ driver I would be ok in the back no problem. 6' front and back, probably ok but not for hours would be my guess.
Another thing to keep in mind, the AMG seats were awesome and fit me like a glove, but bolsters might be uncomfortable if you're wide big in addition to tall big.
