Nice pickup! I also have an '09 BRABUS cabriolet, and I picked up a '17 BRABUS cabriolet last year.
I hope you get a chance to obtain new BRABUS suspension components. I believe your smart is equipped with arguably the best oem suspension in any car I've ever been behind the wheel of. It sticks to the pavement no matter what you do, and the quick, accurate, predictable reflexes are amazing at freeway speeds.
