I am currently looking into acquiring a used 2013 SG Standard but a couple of other possibilities have presented themselves. Since I know nothing about those models/years I figured I would rely on the expertise here. The first one is a 2017 Standard T. I believe that is the traditional style, not the allegedly high performance style. Can anyone give me info on this model - quality, specs, comparison to a 2013 Standard, basically any and all info and opinions would be appreciated. The second is a 2018 Standard ($300 more than the 2017). I would appreciate the same info on this model. Are there any major differences between these two, and what is the consensus here on which one someone should purchase? Thanks in advance folks.
