I'm sure the comments about flower cars being hard to park are based on the full-size, commercial chassis, casket-capable cars. I have been a passenger in such a flower car, and based solely on that experience, I will have to admit that it did seem like a car that was built to only ever be driven forward due to visibility issues. I don't know why they even bother putting a rear window on such cars, it is completely useless, and would be more accurately described as being a sunroof. Now with that being said, I have no doubt that if I owned such a car, I would get used to it.
I'm glad that the standard wheelbase flower car conversions are starting to be mentioned in this thread. That's the kind of flower car I have, converted from a 1979 Lincoln Town Coupe, with an open well for the flowers. Now visibility on that car is a breeze. No matter where I turn my head, I'm looking out a window. I've also heard several PCS members say that the reason they own such a pro-car is because it would fit in their garage.
