hi everyone, I am new to the forum, and I have learned alot from the discussions here.
I am planning to purchase a preowned ct200h, but can't really decide which one is a better deal.. would appreciate any feedback!

1) 2015 f sport, certified pre-own, $15988, with 73k miles. it has premium packages, navigation, as well as comfort packages. seems fully loaded... however, I am not sure if this is relatively on high milage already? this one is really tempting, so I don't mind driving 2 hours to get this one.

2) 2016, based on pics, it is f sport. but website said base trim??? "only" 46k miles, however it is listed at $17495.
this dealer is much more conveniently located, but it is more expensive than first option, and without all the nice features...

3) 2017 model. base trim, despite being the newest year among the three (pretty much I think it is the only advantage), it already has 72k miles.. and I prefer the black ext color more.. is 2017 that much different from older models?

what do you think? thank you very much!

2015 and upward is same except the front bumper trim and maybe how options are packaged. mechanically and functionally there's no difference. The "options" are mostly useless today, i wouldn't consider navigation an upgrade. When that screen fails, you're going to cry and not have a backup cam. I wouldn't put too much weight into "options" on a ct200h other than the f sport package. If the car you like has it, great, but don't lose sleep over it. The heated seats are decent i guess if you need them.

Based on above i'd spend the extra $1500 and go with option 2. a lot less miles for a little extra money. Hard to tell from the pics but option 2 seems a bit nicer cared for.
