Buying a used 2013 or 2014 in Canada

1.) 3G Prius (2010-2015) Standard and Optional Equipment (Some Countries) | PriusChat

It only goes up to 2013 on the page. I switched over to an Excel spreadsheet at that point so you can download that and it'll give you the full range from 2010-2015 (just click on the tabs at the bottom to go between spreadsheets for different years).

Backup camera and bluetooth handsfree are standard on 2013 and 2014 models. I've attached the brochure for 2013 and 2014 if that's easier than an Excel spreadsheet.

2.) Yes. It was made standard in 2012. (It was only available on the Technology Package for 2010 & 2011).

3.) Not too many issues actually. The current side airbag recall only affects 2010-2012 models... Check the condition of the 12V battery (that's the regular car battery.. the one that runs the radio, windows etc). A 2013 model would be as old as 4 years old and may require changing soon. The 12V battery in the Prius is smaller than a regular car battery so it can be drained more easily. I'm still running on my original (7 years now) but I can tell it's a bit weak. Ensure that the cars are fully inspected by a Toyota hybrid technician. A car that has been sitting out for over a month should have at least been moved to maintain HV battery charge.
