In February 1999 I bought Peugeot Zenith, 50 cc, my first scooter.

There are also some other odd stories... considering I drive the scooter 365 days/yr one memorable moment was driving back home from work in the evening when the snow suddenly started... I had to park 1 mile away from the house because the snow was so deep I could not even move anymore... so I just parked it in the snow at the side of the road and walked away, came back to pick it up in two days when the snow melted.
Also, once I was driving home (again from work), it was raining, and it was around freezing, I was going uphill and suddenly, the water started turning into ice... so I was all over the road, but managed to stay on the scooter. The next 5-6 miles I was driving on icy road, while the traffic was completely stopped, the cars could not move (they could not go uphill, and especially not downhill), the buses clogged the road etc.
I had between 2003 and 2005 Piaggio NRG 50 cc LC "extreme", that had lots of mods on it... it was in fact 72 cc, with Leo Vince exhaust, altered carb etc... it was doing 115+ km/h according to speedo and there was a lot of funny looks from the cagers while overtaking them...
Once I was on my Kawasaki ZR-7S when the snow started, but I was lucky enough to come home before it started piling up...
