I have a 7m straight 32amp one for use at work where I have to park face on to the charger. When my home unit gets fitted in a few weeks, I am considering a 3m straight one, if not less, as the back of my car will only be 1m from the charge outlet. Although this will be 16amp, I will buy a 32amp cable as I find the thicker cable just feels much stronger.
As to the rest of the car, just get in and drive. I only had a 10 minute test drive and am now well past 16000 miles in a little over 6 months. If like me, you travel the country all the time, you will love it.
The car is smooth, quiet, comfortable, offers a superb view ahead and eats 500 mile days with ease as long as you stop regularly for fuel. Once you hit save when the electric gauge drops to around 50% and, if like me, you cruise at a Sat Nav regulated 70mph, you should consider 35mpg as doing well, after all, it is an 1800Kg brick. If, however, you will do almost all of your driving in an urban, less than 20 miles a day, environment, using no petrol at all should be an everyday occurence.
Decide which camp you fall into before filling up on the way home with your shiny new car. If you're like me, brim it and don't worry. If you fall to the other camp, no more than £10 because the car will force you to put fuel in after about 3 months to keep the petrol in the tank fresh.
If you want to play with the phone app - heating and cooling settings, door mirrors and locking options and lots more, download an app called WiFi Priority as well, this allows your phone to ignore the car and continue to function properly.
If you travel to London, go on the TfL website and follow the procedure to get free Congestion Charge, it costs a one-off £10. Also, you are allowed to park for free in Westminster, as long as you move to a different street after the maximum for the bay you are parked in, and keep moving all day for free. Remember, somewhere like Berkeley Square is regarded as the same street, so you can only park there once in any given day.
But above all, enjoy!!
