most have humble beginnings, but most trad cleaners around here use a car, its economical. I was talking to a guy the other day 25 years in the business, who worked out of a car. I personally find a kangoo, berlingo, or combo are a good compromise between the economy of a small vehicle and the proffessional look of a van. I wont be going out and buying a Renault traffic for window cleaning trad. No point. I would only do that if I was going to add pressure washing or something to my list of services, but I don't intend on doing that so.
