This is my friend's car, BMW 3 series new engine coupe.
This car has much space, enough to store a surfboard.

Loading up my surfboard (length:6'6") from the trunk after collapsing the backseat .



The board probably won't interfere with my driving.
I think 2 boards and 2 passengers will be OK, and Mileage is pretty good, about 14km/l. The previous model only got about 8km/l, so this is a big improvement.
