speaking from experience, it is much better with 2 cars!
Ive done the comutting on public transport, sucks balls.
I got my r31 which I drive everyday. I can leave it where ever, hell Ive even left it unlocked at places, it goes hard still and can still get sideways and do burnouts in controlled legal environments! But as soon as I get out of that, and into teh 33, the smile is much MUCH bigger!!
It all depends on your budget of course!
When I had bus fare plus weekly train ticket, and then I drove instead....besides the p/p of the car, I was saving over 20 a week by driving,and getting to work and back quicker.
just my 11ty cents
