It depends on the definition of 'big'. Wide people sure as hell don't fit in the sport seat bolsters. Tall people fit, but I don't call tall 'big'.

I'm wide by most people's definition (5'9", 300lb) and have no problem with the sports seats on my MCS.

Define 'wide'. I wear 38" pants and fit very well. My buddy that didn't fit wears 66".

44" pants. Someone wearing 66" pants is gonna have trouble fitting comfortably in most cars I would imagine.

My sister in law's neighbor down at the beach, he is 7' 3 and fit in my mini with out any problems. He did have to have the seat all the way back, but found the car to be very roomy and comfortable!
