Dunno how you can use a car to turn up to work as a long term solution, maybe ok if your just starting out but nothing to me says unprofessional more than turning up to a job in a fiesta with mini trunking sticking out the window
You just look like a part-timer/chancer and wont be taken seriously
nice clean van with sign writing, and smart work embroidered teeshirts is what you should be aiming for eventually
You want to look like a professional business so you can charge accordingly and make the right impression
thieves will break into any van parked in a vulnerable place
without sign writing but rod tubes and ladders on the top its pretty obvious your a tradesmen
you can only invest in better locks, a van vault and decent tool insurance
