How much more expensive is to have a 1984 porsche then a muscle car?

[Nyx]

i found a 1984 porsche 944 solid car only thing bad is needs tranny work the hood for $750

I am very tempted to buy but know they are more expensive to maintain

the owner said the strit is the thing wrong in the tranny dont know what that is?
how much would it be for a new tranny would older trannys or newer trannys fit on the 1984 944?

Thanks!
