snugglybean - Looks like you've already made your decision. Big W have the same capsule I have for around $110 at the moment - cheaper than renting one. It would be a good option for you if you aren't going to use it much.

For anyone reading this post do not rely on taxis being available that will either have a capsule or a bolt to put your own in. We were broken down late at night on the side of a freeway in Melbourne and no such taxi was available. The car had to be towed, it was pouring rain, we could not walk off the freeway, we had to get into a taxi. I had to hold him in the backseat of the car til we got home. Totally illegal I know, but apparently very common.

You may find you use your car a little more once bubs arrives. The first couple of weeks after the birth I could barely walk due to pain (vaginal birth) and relied on the car heavily. It took several weeks before I could walk any great distance with the pram without difficulty so without a car and capsule I would've been housebound.

If you get sick yourself and need to go to the doctor you are going to want to drive. I speak from experience. I could not have walked to my doctors last week while my entire family had the cold from hell. I was completely exhausted from looking after a bub whilst I was sick and could not have managed the walk even if the doctor had been at the end of my street.

When you decide to visit someone for a weekend or go on holiday you will need a capsule. You need a lot of stuff to go away even for a night, trying to cart it around on public transport would be a nightmare.
