Just a quick flashback in history. The largest billboard ever in the world belongs to Citroen, who used up the entire Eiffel Tower from year 1924 to 1932.While oftenly considered a 2nd tier automaker from Europe, Citroen actually started off as a manufacturer that's behind nobody when it comes to being daring. Citroen's cars were already equipped with hydro pneumatic suspensions back in the late 50s when it only started appearing in high end luxury cars in the late 90s for other manufacturers. In fact during an assassination attempt on Charles De Gaulle, the man who liberated the French after the Nazi's collapse failed in killing him when the Citroen DS he was riding was able to travel away at high speed with one trye puncture. (All Citroens with Hydro Pneumatic suspensions could stand firmly upright with either tyres punctures. )
