How much you wanna spend? I just have an old ford connect, cheap but ok for me. If I was buying nearly new, how about these electric ones, nissan do one. Maybe there not great for window cleaning, im not sure, but probably better if your mileage isnt huge (stop/start in local area.) I think the charge dont last as long if fully laden, but its cheap to charge up, and no road tax. I think most would charge up at home. Like I say, i dont really know but probably someone on here has experience of them.
