Maintenance costs and stress for you. Plus you still pay for insurance and gas as well.

That $500 you spent on your engine would pay for one of my bicycles or be half of what I paid for both of them. They are MINE. Now, I might have to replace an inner tube or even a tire here and there with an inner tube being less than $10.00 (I would save money if I did it myself as well).

I'm just thinking about the costs that come with a car and for ME it's just not worth it.

I'd rather contribute to gas for friends and save money for trips than to have my own car
