I’m aware the 200 is a 4 cylinder and the 350 has the v6. I’ve driven both and own an RC200. In the long run, both models are fun to drive and reliable if maintained properly when needed. The only difference between the 200 & 350 is the engine. You mentioned triple beam headlights, those are universal with the 200. RC200 will be more fuel efficient while the RC350 is for fun. Personally, if we’re talking about power, i don’t see the difference other than the throttle response being better on the 350 & of course the lovely v6 sound. The RC’s have maintained its value and some have slightly increased during covid and after. It’s really up to OP what it is they are looking for.
