can a cop search you and your car if you are not driving

i was at my friends house and i looked out the windows and noticed my car was getting towed. in a suburban neighborhood. so i went to talk to the cop outside and see what was going on. the cop told me my car was parked on the wrong side of the road . then he said he smelled weed coming from my open car window and started to search my car , found a couple grams of weed then searched and arrested me. i have been arrested by this cop 8 times now and this is the second time he has done this exact same thing to me.so im wondering if i can sue for harassment or at least get this charge dropped
