TC Cortina - Am I really insane?

[blue fairy]

Hi everyone.

It has been a long while since I posted here, but I have some questions which need quick replies.
Hopefully some of you might be able to help me.

I drive an AU II Futura, which I dislike with a passion. It is boring, slow and doesn't give me much joy unless it is screaming.

I am thinking of selling the Falcon and buying a TC Cortina. This means the Cortina would become my daily driver.

My concerns are the following:

Headlights - Surely there must be something that can be done to make them much brighter? I love the visibility with the AU.

Power Steering - This wasn't an option with the TC's from my understanding. Is it possible to have it done? I love power steering. How difficult would this be and how expensive? Would it be worthwhile having done in a Cortina?

Air Conditioning - I know this can be fixed with an under-dash unit. How effective are these?

Brakes - I love the brakes on modern cars. Really love them. The cortinas I have driven are always spongy. Can this be improved? Cost and difficulty details are also welcome.

Power - I'm worried about the decrease in power.

So, it seems like I have a few issues, most of these I think can be resolved. What I'm after is as much information about the TC Cortina and its abilities to be used as a daily driver.

Thanks for your help,
Kye
