Checking for fluid leaks - Rattle
I am going to see a Fiesta tomorrow, its very cheap and basic but I want to spend a good hour looking over it. I have my dads to compare it with the same engine, so I know what it should sound like etc. However is there any easy way to spot oil/water/brake fluid leaks from underneath considering I can't jack it up?

I am thinking this car could serve as a cheap insure banger until I have real money to spend on a car (this time next year).
