Hi KeKeMaN,
Wow! you have a fabulous collection! 
However, I have to point out that the Strida 3 shown in the picture is a 3.1 instead of 3.2 
Please look at the plastic clips on the wheels. 
When a Strida 5 equipped with 18" wheels, it is called Strida SX. 
Furthermore, this is actually an MAS Special Edition with 18" wheels.
Cheers,
Amuro
