04 Ford Taurus SES worth the repairs?

I have a 04 Ford Taurus SES! I bought it as is {October 2020} from a dealer,  
but wasn't told of all the things wrong with it {I am not a mechanic}!
Found out it has a transmission leak, coolant leak {the hard way} and many
other things wrong with it!
I found out there was a coolant leak by the smoke coming out from the hood
on the passenger side and low coolant all the time {when it started to get
cold and I had to turn the heater on, which didn't last long either}! I did put
Kseal in to keep it from leaking until I could possibly get it in to get it fixed!
Well, driving home {February 2021}, smoke started to come out from under
the hood and then it started to spew through the vents when I stopped at a
red light!! Panic stricken I was racing home hoping to get there before the
car pooted out!! As I am racing I felt a jolt on the steering wheel and then
when I am almost there I gripped harder because I felt the power steering
disappear!!
My question through my story is, will this be worth spending money on a
repair and what could possibly have had happened!! I think I know the
answer to the cost because I think there is more damage in the engine than
just what happened because I've looked all in it and there is a lot of electrical
tape!!
Thanks for your time!!
