i've gotten at a max two snowboards to fit. the larger of the two was a 158cm don't recall the size of the smaller one, had to put the bigger one in first and angle it to fit in the little gap between the rear seats. you may or may not have to take your bindings off depends on how low they can or can't fold down.
like Mazurfer said 11 x 8 sounds right lol,
good luck with the car hunt hope i helped
Zomg.... it spins
