The time has come for me to say farewell to my forum friends since I've now sold my Prius C. It was the most reliable car I've ever owned, with nary a thing that ever went wrong other than a few of the marker lights (easily replaced). And of course it was (until now) the most fuel efficient. Why did I sell it? Well I've mentioned before that I think the Prius is a "gateway drug" to electric vehicles, and sure enough I got addicted. So I've just bought a fully electric Chevy Bolt EV. It's a hoot to drive and I finally feel like I can go on all the joyrides I want without feeling guilty about spewing a bunch of pollution and carbon into the air. I'm lucky to live in British Columbia where virtually all of our electricity comes from hydro-electric dams, so you really can't get any cleaner than an all-electric vehicle. Thanks to everyone for your help and insights, and I hope you and your Prius Cs enjoy long, trouble-free lives!
