Want to replace my car and am looking for an electric vehicle.
Must carry 4 adults, have a range of 60 miles and a speed of about 50mph (80Kmh). Its for commuting and local trips.

Why electric? Petrol is about 15p per mile. Based on what examples I have found an electric car costs about 2-3p per mile to fuel. I expect petrol costs to rise faster than electricity costs. Also there are no carbon emissions from an electric vehicle (my electricty supplier only uses carbon neutral sources).

Finding such a vehicle is a problem. They are either too small, or too slow and short range.

There are commercial vehicles - vans / buses that meet the specs so why so few cars?

The only example I can find is the G-Wiz (Riva) which is too small. You can get cars converted but this is expensive. In any case you need to factor in replacment batteries every so often (800 charges?)

For now I may hang onto my small car. I'll get a large car for heavy loads and long journeys but look into alternative fuels (LPG).

I'll keep looking for that ideal electric car - if anyone knows of such a thing tell me.
