My mums ‘helpful suggestion’ to everything I experience or decision I make in life has been that I could get rid of my car and that would save me money. She’s obsessed. New job? You could work from home and get rid of your car. New house? You could buy close to work and get rid of your car. Need to save money to pay for a holiday/house repairs? Get rid of your car. It’s always my car, not DHs she thinks we should get rid of.
For context DH and I have a car each to get to work, and 2 children who need to be picked up from school and taken to clubs and parties from time to time. Both cars are about 10 years old and owned outright and cost very little in the way of tax and insurance, so even if we did get rid of one it wouldn’t save much money, but would be inconvenient because we’d have to work out a schedule of who needs the car when and potentially be dropped off early or picked up late for things.
