The prosecutor has the option of charging a Class 6 felony as a misdemeanor.
What you can
hope for is that the search is determined to be illegal (perhaps exceeding the scope of the warrant) and what was found in your car cannot be used as evidence against you - and so the charges are dropped.
A more realistic hope, perhaps, is that you only have to pay a fine.
My recommendation is to not piss off the prosecutor or judge. For your appearance in court, dress nicely (no jeans, tee shirts, baseball caps), be polite, don’t smell like drugs.
Good luck.
