I apologize for such a rookie question, but I'm just starting to shop for a used Spyder, and the different models, RT, etc. are a little confusing. I'm 65, and although I don't anticipate any rides over a few hours, I'm interested in comfort instead of sport/performance. I won't need storage or a comfy passenger seat, but I do want a comfortable riding position. I'm flexible on a manual or automatic transmission. What model should I be looking for? Thank you, Jack.
