2003 mini cooper repair estimate?
 

Hey guys,
Im thinking about buying a 2003 Mini Cooper S.

It does need some engine work.
Does anyone have any idea how much it would cost to get the following done?

Result 1:
Replace Head Gasket
Check Rods for Damage

Result 2:
Check Head Gasket
Replace Damage Rod

Result 3:
Replace Head Gasket
Replace Damaged Rod

Result 4:
Used Engine Swap

Thanks for any help!
