6'8?! Forget it! I'm 6'3 and find GTVs uncomfortable to drive; it's not so much leg room as head room. Removing the sun visor saves you from peering under the top of the screen and doing your neck in, but the seat has to be reclined as far as it will go while still allowing me to reach the steering wheel. Luckily I have long arms. If the car has a sunroof, it's worse. If it has electric seats, it's worse. If it has electric seats AND a sunroof, it's barely driveable; I have to kind of tilt my head to one side... a 4-mile road test is about as far as I can go.
