Advice needed for a futur Mustang owner

[Steph]

Hey guys,I previously owned a Corrado VR6 a few years ago. Loved the power and handling.
Car got stolen and now that I few years past, I'm in the market for another car. I want a Mustang GT between 88-92.
I enjoy a car that has alot of power but can also hold corners. Is the Mustang's handling any good ? If not, can it be easily modified
to do so ?

On another note, I told myself that if I did buy this car, I would modify and fix what I can myself instead of taking it to a Speed shop.
The issue with that is I've never really worked on cars myself so I'm missing alot of know-how and experience when it comes to car mechanics. Can anyone suggest me what I should do so I can actually learn to work on my own car ? ( Books, courses ... ).

I appreciate any help and/or advice you guys can give me.

Thanks,

Steph
