Modern Vespa

We've all seen the cryptic serial numbers on our scooters, the Vehicle Identification Number (VIN). These numbers have a fixed format common to all motor vehicles sold in North America after 1980. All VINs have seventeen characters, both alphabetic and numeric. The letters I, O, and Q are not used to avoid being confounded with numerals. A comprehensive explanation and breakdown of the VIN format (including the rather tedious calculation of the so-called "check digit") can be found in the Wikipedia article.

Generally, the format for North America is:

CHARACTER POSITION	INDICATION
1 and 2	Country of manufacture
3	Manufacturer name
4 through 8	Model number
9	Check digit
10	Model year
11	Assembly plant
12 through 17	Serial number

As an example of a VIN on a modern Vespa scooter, the VIN of my 2007 GTS250ie is: ZAPM459Lx7500xxxx. Decoded, this would be:
ZA: Manufactured in Italy
P: Piaggio/Vespa
M459L: GTS 250ie
x: Check digit
7: 2007
5: Assembled in Pontedera
00xxxx: Serial number

This article needs some help from owners of scooters other than the GTS250. My hope is that owners of other scoots will edit this article to enter the 5-character model number from their scooter's VIN. Any other differences would be of interest as well.
