We did. According to our estimates of electricity vs petrol, we would break even (vs petrol car) after about seven years, assuming it was valued at zero at that time. Now we have driven a bit more than we estimated, so it has been less costly than a petrol car. The range has dropped perhaps 5% in the time, which is hardly noticeable. The AC compressor blew up four days before the warranty expired, so let's hope it lasts another few years.

The next purchase is probably 3–4 years in the future. At that time the child is older and can stand some longer road trips, which means we are going to want more range.
