Its quite simple really, most people choose to have their cars repaired by a garage they can trust, and are prepared to pay for the service, the minority choose to repair their own cars, which is fair enough, and luckily they are able to buy parts from the likes of GSF, and also luckily for that minority of people, they don't have to pay around 75k a year in rent, rates, gas/electric, phone services, various different licenses, accountants charges, laundry services, premises insurance, motor trade insurance/liability, burglar alarm services, vending machine services, water rates general property maintenance, the list goes on and on, and the money has to come from somewhere, and I've not even mentioned the staff getting paid! regardless of whether the garage is busy, or not, they still get paid the same... quite simply, the money has to come from somewhere, the mark up on parts is quite small, like I've already said, and is widely accepted by the general public as par for the course, clearly, otherwise we wouldn't be as busy as we are, with never having to advertise
