You have to love tow-n-impound places. I'm not sure if my HOA started hating me but I've had to deal with this place twice now, about 14 days apart.
While they seem fairly nice, they aren't so nice to your wallet. Their hours are squarely at times when you are working, meanining that when you call them "after hours" they will charge you extra to bring someone "off-duty" to get your car out. What a racket.
When I was there the second time someone else had their car towed by Monster as well, only they said Monster just picked their car up in a legal parking spot and hauled it off and never told anyone. While I can't say whether the car was parked legally or not I can say that taking someone's car and telling nobody (mainly the police in this case) seems wrong. To me, that seems like vehicular ransom. The first time they towed at my place I called the police and the police had no record of it being towed. The police called back and said Monster had informed them they were in posession of the car. The second time I didn't call the police so I don't know if they ever informed the police (I already knew who took it so I called them first). I wouldn't doubt if they were into that type of thing honestly.
2-stars for being fairly nice. And 1-star if I could confirm that they were into car-ransom schemes.
