Quick update on how it's going.
The trip for the last 900 miles shows this:
I've used 2.2 gallons of fuel in that time. PugRallye I'm sure will agree that works out at 409mpg
That does include 22 charges, which would cost whoever is paying £20 (hasn't cost me that though). I think a fossil fuel car would have to do about 180mpg to cost the same per mile how I've used it. (purchase price excluded)
I managed to get a sodding puncture on the 3rd day, repaired FOC by TyresNorthants (top blokes). I replacement would have been in the region of £160, not cheap for a 17" tyre IMO.
Everyone who has been in it has commented on the smooth ride, less jiggly than the Prius. Some have even been pleasantly surprised at it's acceleration (given it's an eco car).
The front of it is very very low, I guess for aero reasons, and it scrapes at the slightest gradient change.. but it's just a thin strip of flexible plastic so it's not doing any major damage.
The brakes don't seem as good, or at least they require more force on the pedal to get the job done, like the Prius they seem to lock up earlier than I would like too.
Things I miss from the Prius:
Things I like about the Ampera
Not having to stop at petrol stations (pet hate)
Nicer cabin in general
I agree the initial purchase price is steep, but given it comes with a 8yr 100,000 mile warranty, I think it'd be a cracking used buy in a year.
