SC's can be an intimidating car to deal with, but there is no other like it. I had an '89 that was kept totally stock, but bought the best extended warranty FORD offered, and being a 1st year production car, I needed that warranty. It paid for itself 4 fold.
But.........for some dumb reason I sold it, and bought my wife a '96 Impala SS. BIG time dissappointment. I guarantee you my stock '89 would outrun that heap. After chipping the SS and putting a cold air unit on it, it was better, but I missed my SC and how it acts (you just can't beat the torque and feel).
Saw one with a for sale sign about 18 mo after I sold the '89. I have now had my '92 since '98. It's highly modified, but not a daily driver. I use it for 1) hobby, 2) fun like no other car I can think of, and 3) education - you will learn a lot as it will demand it.
This site is god-send. Many problems experienced and fixes, ideas, mods, have been done before.. I like cars and I see the SC as kind of an exotic, if not at least a rare car.
By the way, ditched the Impala SS about 3 years ago for a Mustang that my son totalled. And ... my wife has a 2002 Pontiac Gran Prix GTP, with, you guessed it, a supercharged engine! Relax folks, I ain't defecting! The GTP was my doing, she only cares about the car's size and amenities, and since FORD doesn't do anything but the Cobra, Lightning, and GT with superchargers, I had to go with Pontiac. And, yes, it ain't no SC!!!!!!!! (but it's no slacker either).
Buy the car, and enjoy the ride, but be ready for some angst now and again.
good luck!
