I've opted for 5 doors for the reasons above. I find the front doors too big on the 3 door.
My garage is pretty narrow and i'm now sick after many years of edging 2 and 3 door cars in the garage and squeezing out with the door wedged on the garage wall [though covered in lurid pink carpet!].
Hang on, it may have something to do with my gut getting bigger too .....
