Do you have any children?
I owned cars from my 18th birthday and a significant amount of my earnings went into them. Now that I am closer to 40 than to 30 and living at a place that can actually provide me with a decent public transport I can see myself not owning a car but the thing is that I have a kid and really don't want to tell my wife and my daughter that we have to go on a bus or wait for a cab to go to the nearby lake for a nice relaxing Sunday afternoon. Also I lease a car for around 200 GBP per month which is less than what I would pay for public transport. With those 200 GBP per month and for a three year lease tires and maintenance are included. What's not to like?
