I see a fair number of Prius's but have only seen 2 HCH2 since I got mine last Dec.
It would be a better comparison to count only 2006 Prius against the HCH2 but I don't know how to identify a 2006 Prius.

With fuel running over a dollar a litre for regular I am surprised there aren't a lot more new Hybrids out there.

 

I've only seen one other 06 HCH since I got mine last week.

Keep your eye's peeled for a silver HCH with tinted windows Hypermile'n westbound down the 401 on weekday mornings... That's me.

 

A week or so ago I saw the first 2 HCHIIs in the GTA other than mine. I have had mine since Dec. 1st, and am thrilled with it so far.

 

In toronto:

if you drive by danforth rd, somewhere near pape ave, there's always a silver HCHII parked facing west on the north side of the road.
If you go to sunnybrook hospital (that's where i work), you'll see 2 HCHII one parked in the rear and one in the front garage and at least 3 Prius II (one is mine).
Also, last week i finally saw for the first time an HCHII in sparkle grey pearl color.
