I didn't get a car until I was almost 30. My girlfriend [now wife] was doing her master's in a city 300 km North, and I had to make a run up there every other week. So I shelled out $800 and away I went. Before I got the car, I just planned ahead. I made sure that I was cycling distance to work, shops, etc. I also made sure that I could walk to the local supermarket. If I ever HAD to have a car, I would just rent for a day or weekend.

Nowadays, my wife and I have made choices that allow us to easily live with 1 car. We live within cycling distance of our jobs and public transit is very close by. Our house cost more because we live close to downtown, but it was totally worth it to be able to walk/bike to the pub/theatre/cinema/restaurants/etc. We spend a lot of time in the mountains, so we use our car to get there, and also for the weekly grocery run. Other than that, it sits in the garage, depreciating. In the summer, we should be able to use the bikes even more, especially for trips to the local farmer's market [saskatoon berry pie and fresh andouille sausage - 'nuff said].

So, can you and your wife live with one car? Hell yes. Can you live with no cars? Probably.
