I'm passing back your feedback and it is very much appreciated Duncan!

One question – did you use any of the settings, or did you even notice that you can add various pieces of data to the report yourself?  Did you notice the various buttons for changing settings and adding info?

It is interesting but I think some of it is a bit off. Here's some feedback (some bits are subjective) which may or may not be useful.

'Include radio AM/FM', actually it is AM/FM/DAB.

Charging information just lists voltage, what would be really useful on this sort of report would be to list the type of connector, the maximum power, and the expected time to full charge.

"FUEL CONSUMPTION Fuel consumption: ; Range 500 km (combined), 311 miles (combined) ; Standard: ECE 99/100*
That looks correct for the official range but I don't understand what the 99/100 means. The official ECE consumption figure is 1.2l/100km (235mpg).

Powertrain Hybrid. I think it would help if you had a distinction here between the E-REV or plug-in hybrid and the ordinary hybrid vehicles. Most of the time the Volt acts as a pure electric car, it only acts as a hybrid when the battery is depleted which makes it very different from something like a Prius.

There is no servicing data and the battery warranty entry is also empty.

"CO2 level – g/km combined Yes"
What does 'Yes' mean here?

Under Electric Power Source it has:
Battery kilowatt hour (kWh) 16
  Range (miles) 24.85

I believe the battery is 16.5kWh (Volts were 16kWh until the late 2012 models when they slightly increased capacity) but I'm not going to argue over half a kWh. Where I do have an issue though is that only 10.8kWh is available to the driver. I think for electric cars you should try to include to figures: the actual capacity and the available capacity as they all restrict the available capacity to maximise battery life.
I'd love to know the source for your range figure? The ECE figure for battery range is 83km/52 miles (which is rarely attainable), the US EPA range is 38 miles. The figure you give is lower than I've ever had.

The pricing and valuation section is way off. Part of the problem here is that when new the Volt like other electric cars qualifies for a £5k government grant, so when you list the RRP as £34,940 it was actually £29,940 and you haven't allowed for that. Also new car prices in this sector seem to have dropped over the last year (the penalty of being an early adopter). For example, the figure you have for current trade '£22,775' is actually about the same as the price being quoted by some dealers for a brand new Ampera (the Volt's more expensive sibling) with the same spec.

I take it the figure you give for insurance doesn't include NCD? It looks scary high. I suppose is about right with no discount but not what I would expect to pay.

Yeah that works a treat – easy enough on he phone as well (only one but I found is when i ticked on terms and conditions – the big red button resized slightly and broke the page width – not by much though – iPhone 4)

But yeah overall – nice!
