Information about the GSX1400

Hello! I have to change to a GSX1400 in the near future (this or at the latest next year). I have already informed myself a little bit about the part. As I have noticed now there are always changes between the different years of construction. Can someone tell me where I can get informations about the different models (best on one side as comparison or so) the part is also built. Only on the HP of Suzuki Germany is built. Is it sold in D as a new car at all? But I would like a used car if it is just as nice as I imagine it. I will also visit the dealer this evening. I think, however, he will want to sell me a new 1200 bandit. That’s why I would like to have some information about the GSX1400 before. Thanks in advance! Greetings Oli
