 Loved my first Prius, a 2007 (I think a level 3 option package - no nav, single CD, etc).  The interior package of my 2017 V (level 4) seems to have been designed by first year interns.  Prime cup holder don't hold 90% of the travel cups I have or have seen.  The power outlets went from 3 easily accessible from the front seat to two; one of which is in the back of the cargo area and not accessible at all by any normal human while riding in the vehicle. The tonneau cover is a bit oddly placed so that one needs to attach a flap to the back seats if it is to cover the whole area; problem is that the attachment only works if those seats are in a slightly reclined position. The straps are solid; guess they hadn't heard of elastic. The miles per gallon on the standard odometer setting is bizzare; constantly going up and down and in no apparent logical way.  The readings on the trip meter work fine but the main odometer reading is useless.  Oh, and the toggle to go from MPH to KM/H has been standard equipment on most vehicles since the 70s; guess it's no longer needed because it simply isn't there, although there appears to be a place for it. What, you have to go to the highest trim package for that? Or is it some other special option?  The navigation system is just OK. My 10 year Garmin was better.  This one thinks I'm off road, I guess, unless I'm zoomed in so far it only shows the next 1/4 mile of map. Not exactly handy.  (Though I really like the display on the speedometer that tells me what street I'm on.)  It also doesn't display the options I've asked for, like speed limit, unless I only have the map displayed (and sometimes not then), and of course, there's no option to have that as the primary display; you have to have something else displayed also as the default. Several other odd "design features" as well.  None are complete deal breakers but very disappointing.  (Oh, and what's with that backup signal?  Not new but NO ONE else has it apparently since everyone who has ridden in my Priuses (just what is the plural?) has ever encountered such a signal that can be heard ONLY inside the vehicle.)Radio is Sirius but that service is of NO use to me, offering only a couple of stations I'd listen to, but I have local ones for those genres. Reception quality is the worst I've had in a radio for at least 28 years (since I've lived in current location). Never had static before, now have it all the time in my location.
