When I am already moving and I hit the gas it sounds like my clutch slips. Is it

What does it do when you hit the gas hard? Does the engine speed raise independent of the vehicle speed? Also, take a look at the estimator link below, if the clutch is 600 and any other materials add to that, then the repair price is a bargain in your situation. https://repairpal.com/estimator/bmw/323i
