Hi and along
My brother is 6'6" and very wide and he fits in my zed, only just may I add though!!
You're budget is pretty low and you will be looking at older models or higher mileage, that's not to say they're bad though, it's more about how they've been looked after. I bought mine for a little more than that (not much more) and I've had no issues at all, others haven't had the same luck. Be patient and the right one will come along
