I have checked my documenation and it says C30-74.
Since i am so happy with the transformation of my car, I am happy for you to take a look. i work near heathrow if you are ever interested, let me know.

For the 4K+ spent, I got 6000 miles 6 month full warranty plus a 2 year warranty on the charger unit itself from Rotrex. I feel it is money well spent, if you want to keep the car for the long term.
and anyway the 0-60 in 6.5 seconds keeps me smiliing every day
