Neighbors inventing parking spot

Ok these guys keep adding a second car to a parking spot that doesn’t exist, blocking my garage partially and making it very difficult/inconvenient for me the white jeep to get in and out safely and without 20 back and forth movements. Backing out into the street is not an option, way too busy of a road and the driveway is very steep. The photos make it look like there’s more room between the spots and the garage units than there actually is. I already emailed management about this and they stopped for a week but now they’re back. The thing that gets me is that there is PLENTY OF STREET PARKING LITERALLY 15 FEET AWAY. So these folks have a lot of nerve. The yellow car isn’t theirs and is a different neighbor but they never go out, I suspect they’re not well off financially and the car may not even work. I don’t know if the previous tenants in my space didn’t care or had a smaller car than mine. Do I keep emailing management? Write a polite note? I don’t care if they want to do this on street sweeping days because I get it, but doing this on a regular basis is super annoying. I just don’t want to create a tense environment but these folks are pissing me off
