Expensive parts in a CAR - how to fix?

What would be top 3 most expensive part to fix in a car. As far as my understnding goes.it wil be

1. Engine
2. Transmission
3. Brake.

(this is for a 10year old ford car )

and rest all easy and cheaper to fix.am referring to expensive here on someting thta would cost me more than 1000 bucks.

Brakes aren't a thousand dollars unless you go to midas. Something like an engine cradle replacement could be up there

Engine tranny, and differential are top 3. Well, I dunno, some cars computer prolly is more than a differential. That's top 4 anyways!

  • Should I be saving our more expensive car? So my wife has a ford and I have a bmw. We mainly use my bmw as it is newer and nicer but despite it being newer it has 3k more miles on it. Should we use the ford more often to save the bmw or just enjoy the nicer car… You only live once?
