FWD vs RWD vs AWD, I want to get the idea out of my head once and for all Options

The Celica is my first car and even tho I've driven all of the wheel configurations mentioned in the thread's topic I don't have that much experience except with FWD obviously.
Ultimately I want a fast car, that sticks well into corners and responds very well to your steering actions. And gets decent millage.
Why I want and don't want RWD in a Celica. It's fun. That seems like the only benefit. It's expensive, time consuming and from my knowledge not the best for cornering since when you push the throttle the back of the car will slide.
Why I want and don't want AWD in a Celica. Great launch. That seems to be the only benefit in my eyes. We don't have much snow in my town and I don't have problem with it anyway to want a vehicle with better traction. I plan on a 3S-GTE and AWD, from my understands, will be a bit slower compared to FWD. And the millage will be worse.
FWD- With that setup the wheels just pull the car out of the corner. I won't spend money with a RWD or AWD conversion. All the speed will be there up front on the wheels on the highway.

What's your opinion?

Over-steer is better than under-steer. As far as I know outside of a V8 swap in a 5th gen, no one has done a RWD conversion. GT-Four conversion is possible, but being you live where you can actually just buy a GT-Four I don't see why you'd bother. Just depends, but some cars the AWD model isn't much worse than the FWD model in terms of fuel economy.

That all being said FWD layouts can be good at cornering, just look at the Integra Type-R. With a good set of springs&struts or coil-overs the Celica is quite capable. Main thing is to remember to use the throttle sparingly, if it all, during hard cornering.
