Without a doubt, vehicles are one of the biggest expenses in most households. Even in a frugal household vehicles can still be immensely expensive. They depreciate, cost fuel, and require maintenance and insurance. What's the best way to deal with an object that requires AT LEAST $100 dollars a month? (Whereas the average person probably spends $500+) Eliminate it.
The easiest way is to move to an urban area, where you can rely on public transportation and bicycles to get anywhere you want to go. This completely eliminates reliance on a vehicle. A bicycle will never require costly maintenance, and public transportation is a one time fee for its use. Even using public transportation daily will be cheaper than a vehicle (Here, you can get a 30 day unlimited ride pass on buses for 50 dollars)
But there's other methods.
If your concern is grocery shopping, or just losing the freedom of getting around, you may consider a few alternatives. You could have your groceries delivered. Some companies do this, and a monthly delivery would come much cheaper than owning a vehicle. Amazon has a LOT of groceries, from Chef Boyardee to your favorite chocolate, and often delivers at a price matching your local Wal-mart, sometimes even below! You could also look into renting a vehicle on that day to buy your groceries and making that occasional trip. This will definitely come cheaper than car ownership if it is infrequent, and would allow you to make other trips as well. There are also hourly rental services springing up that could be even cheaper.
I've done a lot of thinking about how to free myself of the car (Even though I REALLY don't want to, I love driving, but I don't love the fact that it's my second biggest expense...).
Does anyone else have some tricks to share? I'm curious about other ways people control or outright eliminate the costs of their vehicle.
