Dayum Tony, you're a scrappy dude
I'm 6'2, 185 and can sit comfortably in the back seats as long as someone my height isn't in the front also, need the front seats forward for leg room.
I've had 4 235 45 17's on rims in the rear with the seat folded down, and still had the whole area from what would be the back of the seats to the back empty. I love my TI for its practicality. Manual/auto is up to your preferences. Myself, if I bought an auto it'd be swapped ASAP
